Okay so I'm on the birth control Trinessa. I just started it a little over a week ago. The pamphlet with it said that within 7 days the birth control would be in full effect. My boyfriend and I had sex exactly on the 7th day, and he didn't come inside me but we used a condom first and he came in it, pulled it off and wiped his thing off with some napkins. Shortly after we had sex again without a condom. Should I be concerned of pregnancy?
