Question 1

How is the ovulation date calculated?

Accepted Answer

Ovulation generally occurs 14 days before the next period (luteal phase). If your cycle is 28 days, ovulation occurs around day 14. For irregular cycles, subtract the luteal phase (usually 14 days) from the total cycle length.

Question 2

How long does the fertile window last?

Accepted Answer

The fertile window lasts approximately 6 days: the 5 days before ovulation plus the day of ovulation itself. This is because sperm can survive up to 5 days in the female reproductive tract, while the egg is only viable for 12-24 hours.

Question 3

What are the best days to get pregnant?

Accepted Answer

The best days to conceive are the 2 days before ovulation and the day of ovulation itself. Pregnancy probabilities are: 27-33% the day before ovulation, 25-28% two days before, and around 15% on ovulation day.

Question 4

What symptoms indicate ovulation?

Accepted Answer

Ovulation symptoms include: increased vaginal discharge (egg-white consistency), mild pain or sensation on one side of the abdomen (Mittelschmerz), increased libido, slight rise in basal body temperature, and breast tenderness.

Question 5

Can this calculator be used as contraception?

Accepted Answer

No. This calculator is not a reliable contraceptive method. Menstrual cycles can be irregular and ovulation can vary due to stress, illness, or other factors. Consult your doctor about safe contraceptive methods.

Question 6

What is the luteal phase and why does it matter?

Accepted Answer

The luteal phase is the period from ovulation to the start of the next period. It lasts 12-16 days (typically 14). It is fairly consistent for each woman. A short luteal phase (less than 10 days) can make embryo implantation more difficult.
