How Does This Ovulation Calculator Work?

This ovulation calculator helps calculate your most fertile days. It does so by estimating when you're most likely to ovulate, i.e. it counts back 14 days from your next period’s expected start date. If you have a typical menstrual cycle length of 28 days, your next period should start typically around 28 days after your last period’s first day.

Your fertility window includes your ovulation day as well as the 5 days before it. However, remember that you could also conceive during the last 3 days of this window.

What Are The Tips For Getting Pregnant Fast?

Some tips to help you increase your chances of getting pregnant fast:

  • Get a preconception checkup: Check if you need to take prenatal vitamins like folic acid that helps protect against some birth defects.
  • Track your fertility and ovulation periods: This will help you know when you’re the most fertile and likely to conceive.
  • Have sex more often.
  • Avoid gravity-defying positions: such as sitting or standing during intercourse.

Your Frequently Asked Questions

Ovulation occurs when one of your ovaries releases a mature egg for fertilization during your menstrual cycle.
If a sperm fertilizes the released egg, then this fertilized egg moves to the uterus and implants itself there. This results in conception.
If unfertilized, the egg breaks down and the uterine lining (lining of the womb) is shed along with the egg, starting your period.

Vaginal discharge is a secretion produced by vaginal and cervical glands. It helps keep your vagina and reproductive canal healthy and clean.
Vaginal discharge’s color, consistency, and amount can vary from person to person. It also changes from day to day, based on where you are in the menstrual cycle:

Day 1 to Day 5:Vaginal discharge is normally red or bloody, since the uterine lining is being shed.

Day 6 to Day 14:After you’ve had your period, you may notice that your vaginal discharge has reduced in amount. As the egg begins to grow, the cervical mucus, a major part of the vaginal discharge, turns cloudy, white or yellow, and possibly sticky.

Day 14 to Day 25:Shortly before your ovulation starts, the cervical mucus becomes thin, slippery, and similar to egg whites in its consistency. After your ovulation period ends, the mucus returns to becoming cloudy and white or yellow. It may also feel sticky.

Day 25 to Day 28:The vaginal discharge lightens in color and reduces in quantity before another period starts.

Women with the average 28-days in a cycle usually ovulate on or around Cycle Day 14. The numbering of cycle days starts over if a pregnancy does not begin, and the woman starts her period.

Ovulation lasts for 12 to 48 hours, but you are potentially fertile for up to seven days, and maybe up to 10 days. This is because sperm can survive up to five days in the female reproductive tract.

When taken correctly, ovulation tests are approximately 99% accurate in detecting the LH (luteinizing hormone ) surge, hormone that triggers ovulation & your fertile period.

As you approach ovulation, your cervix will become soft, high, open, and wet – you can remember this with the acronym SHOW. After ovulation, these signs reverse and the cervix becomes firm, low, closed, and dry.
