Seriously my pet peeve about this site is people asking if they could possibly be pregnant after having unprotected sex. Seriously! How the hell could a bunch of strangers answer this with any accuracy? Here's a quick answer: if you had unprotected sex you could be pregnant. We can't tell. I'm sorry but we can't. Take a pregnancy test or go to the doctor and have a blood test. You can get tests that are completely accurate from 5 days before your period is due. If it's earlier than that don't take six million tests, Just WAIT AND TAKE AT THE RECOMMEND TIME. Cheers and good luck!
