I'm 16, and I am on Triqular birth control, I've been on them for a year and half, and I have NEVER skipped a pill before! My doctor said, they're 99% chance, I can't get pregnant! While taking them properly, which I do! My boyfriend usually doesn't sperm in me, but I let him about 3 weeks ago, for the first time, (it's the first time any guy as spermed into me) he spermed about 30 mins before also, but NOT in me... So that means the second load he done wasn't so much.. But wash the smallest amount. ~ I usually come on my period on a Friday, or a Saturday, I didn't come on today, I was wondering if it's any chance? I've been taking my birth control regularly, never have skipped a pill, and he spermed into me once, it was his second load..
