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<img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile"><img alt="" class="inlineimg" src="/img/vbsmilies/smilies/bag.gif" style="border:0px solid;" title="Bag">: I would notice this somewhat when I would cycle with DD#1 but when she was older like 18 months or so.
