I am nursing DD 7 months. I have been cycling since she was 3 months old. I am due yesterday for AF but know that during BFing it can be very irregular and since I didn't chart I really don't know when I ovulated. I have noticed a much lowered milk supply the last 2 days. Can early pregnancy cause a lowering of supply as hormones switch? that quickly? It is a distinct possibility, but I'd rather be in denial at the moment thank you very much: I would notice this somewhat when I would cycle with DD#1 but when she was older like 18 months or so.
