Q: My cycle is over 45 days long, what should I do?
A: Your menstrual cycle starts on the first day of your period, the first day when you bleed, and it ends the day before the next period. The length of regular menstrual cycles is determined by when you ovulate, and your period usually begins about 14 days after ovulation. Cycles as long as 45 days or more are usually associated with not ovulating (anovulation) and doing a fertility chart will help answer your question. If you have cycles that last that long but you do ovulate then chances getting pregnant are decreased because you ovulate less often and the lining of the uterus is less likely to accept the fertilized egg for implantation because it's not optimal.
