Hello I recently had a baby 2 1/2 months ago. I began taking birth control pills 1 1/2 months ago. My husband and I had sex yesterday and I took my birth control pill 4 hours late (for the first time). I think I am just being paranoid because I don't want to get pregnant again so soon but should I take the morning after pill and if so is it safe while I'm nursing my baby?

You are more than likely safe even with the 4 hour delay, but the morning after pill is safe to use if necessary, but obviously not to be used as a regular form of birth control.

Main thing you may notice could be a dip in milk supply so over the next several days be sure to nurse on a regular basis and add a couple of feeds over a few days if need be to boost supply.
