Alright ladies. In Need of advice. My SO and I went out tonight since the first time in oh gosh over a year. We left the baby with my dad. Went to the bar had a few drinks, so on.

Well we ended up messing around and the condom broke. He said he thinks he pulled out in time, but wants me to take plan B. Well I'm breastfeeding. I read that your milk supply could go down for a few days then come back, but I also read it could disappear. I don't know if I should take it, or maybe there's another way to go about this? Has anyone breastfeeding ever taken it?
