i'm 16 years old. I'm on the birth control Ortho Tri-Cyclen Lo. and i've been on it for about a month and a half. i take it every single day and at roughly the same time. my boyfriend and i have had sex a couple times with a condom during this time and he did not ejaculate at all so i'm not worried about that. however, a couple nights ago we had sex without a condom and he pulled out and came on my stomach. i was just wondering if i was protected from pregnancy by now? and should i be worried about it?
