Calculate my cycle



*First day of your cycle = First day of last period
*Luteal phase = Days between ovulation and next period. Usually 14 days.

Your ovulation, day by day

A new cycle starts here!
Fri, October 12, 2018
day 1, menstrual phase.
16 days to your next cycle.
• Although the menstrual cycle lasts typically 3 to 5 days, anything between 2 to 7 days is considered normal.
Sat, October 13, 2018
day 2, menstrual phase.
15 days to your next cycle.
• The average bloodloss during menstruation is 35 milliliters (1.2 fl.oz) and anything between 10 and 80 ml (0.33 - 2.7 fl.oz) is considered normal.
Research has indicated a long menstrual cycle can be shortened by placing a clear 100w lamp beside the bed five nights before ovulation.
Sun, October 14, 2018
day 3, follicular phase.
14 days to your next cycle.
• Because of the bloodloss during the monthly menstrual cycle, women require more iron then men.
• The lining of the uterine wall is now at its thinnest. The levels of progesterone and estrogen are now at their lowest.
As a result of the increase in Follicle Stimulating Hormone (FSH), five to seven tertiary follicles will be utilised. One of these will become the egg cell.
• Sperm lives on average 1 to 5 days but can survive up to 8 days. If you are trying to conceive the best time to try is between now and the next 5 days. Bcause ovulation varies among women it is suggested between now and the following 9 days is the optimum time to try to conceive.
Mon, October 15, 2018
day 4, follicular phase.
13 days to your next cycle.
• Many women experience uterine cramps during menstruation.
• The selected follicles have been developing for almost a year in a process known as folliculogenesis. The follicles vie for dominance.
• Today and for the next three days is the best time to try to conceive.
Tue, October 16, 2018
day 5, follicular phase.
12 days to your next cycle.
• Due to the influence of several hormones most follicles will die in a process known as atresia. One or two will remain and become mature follicles.
• If the egg matures it will produce enough estradiol to begin the process of secretion of (LH) luteinizing hormone.
Wed, October 17, 2018
day 6, follicular phase.
11 days to your next cycle.
• Fertility increases as the follicular phase progresses.
• During an average cycle the release of LH begins around day 12 and lasts approximately 48 hours.
Thu, October 18, 2018
day 7, ovulation phase.
10 days to your next cycle.
• As the remaining follicles mature they produce more estrogen. The estrogen ensures that a new edometrial layer is formed in the womb and that cervical glands produce fertile mucus.
• Ovulation: The ovaries release the egg which travels into the fallopian tube. IF fertilisation takes plae it will occure today or tomorrow in this fallopian tube. An egg can be fertilised up to 48 hours after release.
Fri, October 19, 2018
day 8, luteal phase.
9 days to your next cycle.
• The time required to recruit and select the most dominant follicles can result in variations in the length of menstrual cycles.
• After ovulation the ovarian follicle which released the egg changes and is known as the corpus luteum or yellow body. Over the next 14 days this will produce progesterone. Progesterone helps prepare the uterus for implantation and maintains the lining which provides food to the newly implanted egg.
Sat, October 20, 2018
day 9, luteal phase.
8 days to your next cycle.
• Approximately 24 to 30 hours after fertilisation the first mitosis or cell division takes place.
Increased progesterone raises the body temperature in order to provide the optimum conditions for the egg. Body temperature is increased by 0.25 to 0.50 of a degree. Women who take note of their basal body temperature will notice that the luteal phase has begun.
Sun, October 21, 2018
day 10, luteal phase.
7 days to your next cycle.
• If fertiliation has taken place the egg and spermatozoon are known collectively as the zygote. The zygote will travel through the fallopian tube to the uterus. This journey of 10cm or 4 inches proceeds at a rate of 1.5cm or 0.6 inches.
Mon, October 22, 2018
day 11, luteal phase.
6 days to your next cycle.
• If the released egg is not fertilised within 24 to 48 hours, the rest of the luteal phase will be infertile.
Tue, October 23, 2018
day 12, luteal phase.
5 days to your next cycle.
Once the division of the zygote cells increases to 16, the collection of cells are known as a morula.
Wed, October 24, 2018
day 13, luteal phase.
4 days to your next cycle.
Fri, October 26, 2018
day 15, luteal phase.
2 days to your next cycle.
• A fertilised blastocyst attaches itself to the uterine wall. At the point where the cell meets the uterus the umbilical cord and placenta begin to form. This implantation can happen today or within the next few days.
Sat, October 27, 2018
day 16, luteal phase.
1 days to your next cycle.
• Shortly after the implantation of the growing embryo, other changes will take place in the body. One of the first signals is the secretion of pregnancy hormone human Chorionic Gonadotropin (hGC). This is the hormone picked up by pregnancy tests.
