I had a m/c April 2006. I didn't get my first period until June 1st (that's two MONTHS of waiting). I became pregnant in mid-June and now have a beautiful 8-month-old girl (who is actually sleeping in my arms right now... makes it hard to type). Anyway, as you can see, we tried immediately and hit jackpot. Some women have become pregnant BEFORE they even get their first period after a m/c. But the reason your doc wants you to have two cycles is to make sure your body is ready. It is a traumatic experience on your body. BUT women have healthy babies after m/c all the time. So do what you think is best. I did and I wouldn't give up my daughter for anything in the world. I had ZERO complications. So you can wait until next time around or get busy now! Good luck! And please, if you don't get pregnant right away, don't worry! Just keep trying. I'm not trying to make it sound like getting preggo is easy for everyone by telling my story. I just wanted you to know that I did TTC immediately and it went very well for me.
