Re: How do i calculate when to TTC....

If my periods are irregular, will it be harder for me to get pregnant?
Most women have about 12 periods a year, but some skip months or don't get a period at all. Stress, heavy exercise, dramatic weight loss or gain — all of these can cause interruptions in your period. The more irregular your period is, the more difficult it is to predict ovulation. You can figure out the days you're most likely to be fertile by tracking when you ovulate each month.

Say your cycle is 28 days one month, 21 days the next month, and 32 days the following month. Keep a record of your menstrual cycles for several months. Then subtract 17 from your shortest cycle and 11 from your longest cycle. The days in between the two are the ones you're most likely to be fertile. If your cycles are irregular and more than 35 days apart or longer, you should consider seeing a fertility specialist to check for other causes of an irregular cycle, such as polycystic ovarian syndrome (PCOS ), ovarian dysfunction, thyroid disorder, excessive weight loss or an elevated prolactin level.
