Hi Emma,
My doc told me with the mini pill you have to start taking it when the baby is 21 days old (21 days after birth) or you have to wait for your period.... thats what my doc said so just check with yours and see what they say.
I never had any problems with it interfearing with my BM... Jacob didnt seem to change his patterns when I started taking it.
I found it fine... the only thing that I didnt much like was that once my period started again there is no break in the mini pill so you dont get your period 'regularly' could you say....... BUT!!! BEWARE!!!! I stopped BF and was about to go OFF the mini pill so I could get back on the normal pill.................... and fel pregnant again!!!!!!!!!!! So I was still on the mini pill but had just stopped feeding....... WHOOPS!! :P

So definatly dont miss one!!!

Good luck with it and I hope all is well for you and DH and your precious new edition
