Many drs will tell you to wait 3 months after going off bcp. My sister got pg her first cycle off of the pill. Her ob told her that you are most fertile the first 3 months off the pill. The reason they like you to wait is so they can more accurately predict a due date. There are many ways that you can increase your odds of conceiving. Chart your temperature, cervical mucous and take ovulation predictor tests. A great website to try is: Pregnancy Land - Affordable Pregnancy and Ovulation Tests luck!
