Hello, and I hope I can help you today.
When you have irregular menstrual cycles, it is difficult to pinpoint the time of ovulation each month.
Ovulation generally occurs about 14 days before your period starts. So if you count 2 weeks backwards from the date that your period starts, you can figure out by looking a few months back what your typical window of time is typical for your ovulation.
If you have intercourse every other day from two days before your typical ovulation time until you either feel PMS symptoms or your period comes, whichever comes first, there should be enough active sperm around when you typically ovulate for you to conceive.
For more accurate estimation of your ovulation, there are kits called ovulation projectors that can be bought over-the-counter in a chemist or pharmacy. These kids have test strips for your urine that check for certain hormone that is released when you are about to ovulate. These test strips can also be useful if you do not have regular cycles when trying to conceive.
If you and your partner try unsuccessfully for one year to get pregnant, there may be a medical reason involved in why you are not conceiving. At that point, you may want to consult with your gynecologist or
fertility specialists.
I hope I was able to adequately answer your question today, and that this information was helpful.
Best wishes,
Dr. Brown
