I did, I stopped feeding DS4 so that we could conceive as I had never been able to fall pg while b/fing.

But saying that, I fell pg this time around while still feeding Julian 4 times a day/night and only had AF twice before I fell pg. I got AF back at 14 and a half months.

I've also heard of some women that have fallen pg while b/fing and haven't had AF back, so you could still fall pg. Maybe trying fertility friend and start charting your temps and just see if there is a pattern, you just never know.
