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!
Mon, April 23, 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.
• If the egg matures it will produce enough estradiol to begin the process of secretion of (LH) luteinizing hormone.
Tue, April 24, 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.
• During an average cycle the release of LH begins around day 12 and lasts approximately 48 hours.
Wed, April 25, 2018
day 3, ovulation phase.
14 days to your next cycle.
• Because of the bloodloss during the monthly menstrual cycle, women require more iron then men.
• 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.
Thu, April 26, 2018
day 4, luteal phase.
13 days to your next cycle.
• Many women experience uterine cramps during menstruation.
• 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.
Fri, April 27, 2018
day 5, luteal phase.
12 days to your next cycle.
• 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.
• 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.
Sat, April 28, 2018
day 6, luteal phase.
11 days to your next cycle.
• The selected follicles have been developing for almost a year in a process known as folliculogenesis. The follicles vie for dominance.
• 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.
Sun, April 29, 2018
day 7, luteal phase.
10 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 released egg is not fertilised within 24 to 48 hours, the rest of the luteal phase will be infertile.
Mon, April 30, 2018
day 8, luteal phase.
9 days to your next cycle.
• Fertility increases as the follicular phase progresses.
Once the division of the zygote cells increases to 16, the collection of cells are known as a morula.
Tue, May 1, 2018
day 9, luteal phase.
8 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.
Thu, May 3, 2018
day 11, luteal phase.
6 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.
Fri, May 4, 2018
day 12, luteal phase.
5 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.
Sat, May 5, 2018
day 13, luteal phase.
4 days to your next cycle.
• The quantity of hCG increases but may still be too low to be recognised by the standard over the counter pregnancy test. The amount of hGC doubles every 2 to 3 days.
Sun, May 6, 2018
day 14, luteal phase.
3 days to your next cycle.
• An hGC bloodtest will now be able to detect the slight increase in hCG but it is still too early for a urine test to be accurate.
Mon, May 7, 2018
day 15, luteal phase.
2 days to your next cycle.
Tue, May 8, 2018
day 16, luteal phase.
1 days to your next cycle.
• From today a sensitive urine based pregnancy test might be able to detect hGC for a positive result. However, a negative test does not mean there is no pregnancy but can indicate that hGC levels are still not sufficient to be measured.
A new cycle starts here!
