I agree that your fertility sounds pretty normal When AF returns you'll know your body is ready to go again (altho you can ovulate & fall pregnant while breastfeeding without any AF!). And you know that your DH has the swimmers to make babies, so don't stress too much.

Our situation was different, but I had similar fears. I have (had?) PCOS and had no cycle for 10 months, so had to go on meds to fall pg with Tallon. However, 3 months into breastfeeding, even though it was around the clock still, AF turned up, and my cycle was like clockwork from then on. I did chart when TTCing, coz It gave me something to do LOL, and we also wanted to try for a girl this time So I reckon the pregnancy, if anything, improved my fertility (fell pg 2nd attempt with NO meds this time! and still breastfeeding!).

I'm sure you'll be just fine when it comes time
