Hi Finsmum: I found that my symptoms leading up to AF changed a lot after I had my DD (Daughter). I also had months where i really couldn't tell if I was getting AF or if i was pg. I have had two pg (two mc) and am now pg a third time since DD. I was sure I was pg last month because of the type of cramping i was getting and.. nothing. ANd I was sure AF was coming this month and got a big surprise when she didn't and BFP. I think pg must change our bodies and that they change with time too. There doesn't seem to be any logic to it. It's interesting your DR told you to stop breastfeeding. If you have had a normal cycle back and have fallen pg in the last few months I would have thought the breastfeeding isn't making any difference to your fertility now (except perhaps that you need to eat enough to keep you in good physical shape for BF'ing and TTC). Wishing you all the best TTC.
