... start whenever I wanted so I started that day about a week and a half after my last period. Five days later my husband and I had unprotected sex. She did not say Anything about a back up method so read the instructions and it said to wait a week before having unprotected sex after starting the pill. I was wondering if anyone else has been in the same or similar situation and how it turned out for them. I like kids but we are still very unsure. Plz help! Thanks!
