My baby is now 7 months old and my AF has not returned. I exclusively expressed for 4 months, then over the last 3 months have reduced this and combination fed. I'm now down to expressing just once every 2 days. I'm a little concerned about AF not yet returning, given that I've drastically reduced the amount of expressing. I know exclusively bf can delay periods but it's been 3 months since I was doing the equivalent of ebf. Has anyone else experienced this?
