My boyfriend & I had sex last night & he ejaculated a tiny bit inside me. Im on the 28 day tri-legest birth control packet, but last night I was only on day 5. Today will be the 6th, & he's getting me Plan B sometime today. The pill isn't fully effective until the 7th day. I don't wanna hear "If you're on the pill you don't need Plan B." It hasnt been a full week of me starting the tablets & Im just being extra safe. I'm too young to be pregnant. I just wanna know if it's okay to take Plan B while only being on day 6.
