The morning after pill is just a heavy dose of the regular pill from what I have been told you take 2 on the first day and two the secon day. It needs to be taken a certain time after DTD to be efective.

I'm pretty sure that you wouldn't be able to take it and BF. I think you should be fairly safe given that you haven't had AF, and are reg BF. All the best. BTW don't eel stupid, happens to us all :-)
