Hey Ladies! I'm back! Soooo my answer to this problem is spend A LOT A LOT A LOT of time with a lady close to your age who you KNOW has regular AF's. I've been irregular my whole life, except for the 2 years I was on BC. When I got off BC my periods were so irregular I didn't know what to do. Then I moved in with my sister-in-law who happens to have very regular cycles. Within a month of living with her I finally got AF after 3 1/2 months and the following month AF came a little late but it was only b/c my body was regulating with her cycles. (Her AF came a few days before mine). I'm expecting my AF this month (if I don't get pregnant) to show up again within a few days of hers. I'm so excited about this b/c, even though AF means I didn't get a sticky bean this month, it also means I have improved my chances of it in the future! Good luck to all! I'm heading for the cause I know I'm fertile!!!!
