Days from now Date Day of cycle Phase Days to your next cycle What's happening?
-19Monday, October 13th ,2014 1st day menstrual 31 days to your next cycle. • The menstrual phase usually lasts 3 to 5 days, but anywhere from 2 to 7 days is considered normal
-18Tuesday, October 14th ,2014 2nd day menstrual 30 days to your next cycle. • The average blood loss during menstruation is 35 millilitres with 1080 ml considered normal
-17Wednesday, October 15th ,2014 3rd day menstrual 29 days to your next cycle. • Because of this blood loss, women have higher dietary requirements for iron than do males to prevent iron deficiency.
-16Thursday, October 16th ,2014 4th day menstrual 28 days to your next cycle. • Many women experience uterine cramps during the menstrual phase.
-15Friday, October 17th ,2014 5th day follicular 27 days to your next cycle. • The lining of the uterus is at its most thin. Levels of estrogen and progesterone are at their lowest.
• Through the influence of a rise in follicle stimulating hormone (FSH), five to seven tertiary-stage ovarian follicles are recruited for entry into the next menstrual cycle
-14Saturday, October 18th ,2014 6th day follicular 26 days to your next cycle. • These follicles, that have been growing for the better part of a year in a process known as folliculogenesis, compete with each other for dominance.
-13Sunday, October 19th ,2014 7th day follicular 25 days to your next cycle. • Under the influence of several hormones, all but one of these follicles will undergo atresia, while one (or occasionally two) dominant follicles will continue to maturity.
-12Monday, October 20th ,2014 8th day follicular 24 days to your next cycle. • Your fertility increases throughout the follicular phase
-11Tuesday, October 21st ,2014 9th day follicular 23 days to your next cycle. • As they mature, the follicles secrete increasing amounts of estradiol, an estrogen. The estrogens that follicles secrete initiate the formation of a new layer of endometrium in the uterus. The estrogen also stimulates crypts in the cervix to produce fertile cervical mucus
-10Wednesday, October 22nd ,2014 10th day follicular 22 days to your next cycle. • The time needed for recruitment of the follicles and selecting the best (dominant) follicle for the ovulation causes variations in the length of the cycle.
-9Thursday, October 23rd ,2014 11th day follicular 21 days to your next cycle.
-8Friday, October 24th ,2014 12th day follicular 20 days to your next cycle. Research supports the suggestion that a bright 100W bedside lamp used on 5 consecutive nights prior to ovulation can cause reduction of long menstrual cycles.
-7Saturday, October 25th ,2014 13th day follicular 19 days to your next cycle. • Normal sperm life inside a woman ranges from 1-5 days, though a pregnancy resulting from sperm life of 8 days has been documented. If you are trying for a baby, it would be a good time to try today and in the next 5 days. Because ovulation dates are different for every woman and each cycle, it is suggested that if a woman wants to conceive, the most fertile time occurs between today and the next 9 days to come.
-6Sunday, October 26th ,2014 14th day follicular 18 days to your next cycle. • This day (as well as the the next 3 days) is a good day to try for a baby.
-5Monday, October 27th ,2014 15th day follicular 17 days to your next cycle. • When the egg has matured, it secretes enough estradiol to trigger the acute release of luteinizing hormone (LH).
-4Tuesday, October 28th ,2014 16th day follicular 16 days to your next cycle. • In the average cycle this LH surge starts around cycle day 12 and may last 48 hours.
-3Wednesday, October 29th ,2014 17th day ovulation 15 days to your next cycle. • Ovulation: The release of the ovum. The egg is swept into the fallopian tube. If fertilization occurs, it will happen in the fallopian tube, today or tomorrow. (A released egg can be fertilised for up to 48 hours)
-2Thursday, October 30th ,2014 18th day luteal 14 days to your next cycle. • After ovulation, the follicle which held the egg transforms into the corpus luteum. It will produce progesterone for approximately the next 2 weeks. Progesterone helps forming a lining receptive for implantation and supportive of the early pregnancy.
-1Friday, October 31st ,2014 19th day luteal 13 days to your next cycle. • 24-30 hours after fertilization the first cell division (mitosis) takes place.
• Progesterone raises the body temperature to provide a fertile environment for the ovum by 0.25 C to 0.5 C (0.5 F to 1.0 F), thus women who record their basal body temperature on a daily basis will notice that they have entered the luteal phase.
TodaySaturday, November 1st ,2014 20th day luteal 12 days to your next cycle. • If fertilization of an egg has occurred, the egg and sperm united are called a zygote. It will travel through the fallopian tube, making its way to the uterus.
1Sunday, November 2nd ,2014 21st day luteal 11 days to your next cycle. • If an egg is not fertilised within 24-48 hours of ovulation, the rest of the luteal phase is considered to be relatively infertile.
2Monday, November 3rd ,2014 22nd day luteal 10 days to your next cycle. The zygote's rapid cell division from 2 to 4 to 8 now reached 16 cells. By this day the ball of cells is called a morula.
3Tuesday, November 4th ,2014 23rd day luteal 9 days to your next cycle.
4Wednesday, November 5th ,2014 24th day luteal 8 days to your next cycle. The morula's rapid cell division from 16 to 32 to 64 now reached 128 cells. A cavity is formed within the ball of cells. It is now called a blastocyst or blastula. Very soon the blastocyst will have so many cells that individual cells are no longer recognizable
5Thursday, November 6th ,2014 25th day luteal 7 days to your next cycle. • A fertilised blastocyst will implant itself into the uterine. The point of implantation becomes the origin for the placenta and umbilical cord
6Friday, November 7th ,2014 26th day luteal 6 days to your next cycle. • Shortly after implantation, the growing embryo will signal its existence to the maternal system. One very early signal consists of human chorionic gonadotropin (hCG), a hormone that pregnancy tests can measure
7Saturday, November 8th ,2014 27th day luteal 5 days to your next cycle. • The level of hCG is increasing, but still too low to measure with a home pregnancy test. The level will double every 2 or 3 days.
8Sunday, November 9th ,2014 28th day luteal 4 days to your next cycle. • a hCG blood test may now see an increased hCG level. It is still too early for a home pregnancy test measuring the hCG in the urine test.
9Monday, November 10th ,2014 29th day luteal 3 days to your next cycle.
10Tuesday, November 11th ,2014 30th day luteal 2 days to your next cycle. There is a good chance that a home pregnancy test can pick up enough hCG to confirm a pregnancy. A negative test doesn't mean you're not pregnant, there may simply not be enough hCG yet because it is too early after implantation.
11Wednesday, November 12th ,2014 31th day luteal 1 days to your next cycle. • if the egg is not fertilised and does not implant, the corpus luteum will disintegrate after approximately two weeks, causing the drop in progesterone levels that signals the start of menstruation and the beginning of a new cycle

Things to know

  1. HPT means Home Pregnancy Test. HPTs are cheap and come over the counter.
  2. hCG is human Chorionic Gonadotropin. A pregnancy test measures hCG. hCG production starts at an early stage of development, just a few days after conception, before implantation in the uterus and appears in the blood and urine of pregnant women
  3. 85% of normal pregnancies will have the HCG level double every 72 hours.
  4. If you are very early in your pregnancy, and the HCG level is below 25-50 mIU/mL, the test will be negative.
  5. The American Pregnancy Association cites the following chart as normal ranges of hCG for the number of weeks after the womans last menstrual period (period of 28 days):
    3 weeks: 5 - 50 mIU/ml
    4 weeks: 5 - 426 mIU/ml
    5 weeks: 18 - 7,340 mIU/ml
    This shows that our suggested date may work for some, while it is too early for others.
  6. Some normal pregnancies will have quite low levels of HCG - and deliver perfect babies.
  7. There are two types of pregnancy tests. One tests the blood for the pregnancy hormone, hCG. The other checks the urine for this hormone. You can do a urine test at home with a home pregnancy test. You need to see a doctor to have blood tests.
  8. Blood tests can tell if you are pregnant about 6 to 8 days after you ovulate
  9. If a HPT says you are pregnant, you should call your doctor right away. You doctor can use a more sensitive test along with a pelvic exam to tell for sure if you're pregnant. Seeing your doctor early on in your pregnancy will help you and your baby stay healthy.
  10. Testing the urine first thing in the morning may help boost accuracy.
  11. Most brands tell users to repeat the test in a few days, no matter what the results. One negative result (especially soon after a missed period) does not always mean you're not pregnant.
  12. Visit www.fertilityplus.org for a good overview of HPTs.
  13. The amount of hCG in the urine is different for every pregnant woman. So, some women will have accurate results on the day of the missed period while others will need to wait longer.
  14. Some home pregnancy tests are more sensitive than others. So, some tests are better than others at spotting hCG early on.
  15. In a 2004 study, researchers tested the accuracy of 18 HPTs sold in retail stores. They found that only one brand consistently detected the low levels of hCG usually present on the first day of the missed period. This was the First Response, Early Result Pregnancy Test. The other tests missed up to 85% of pregnancies on the first day of the missed period. Most tests accurately confirmed pregnancies one week after the missed period.
  16. If your HPT is negative, test yourself again in a few days or 1 week. If you keep getting a negative result but think you are pregnant, talk with your doctor right away.
