Don't beat yourself up over this! You guys are very smart for always using protection. It's better to find out than to be sitting there wondering. Like the above poster said, you should probably get a pregnancy test. The more you worry, the more you'll put off your period and convince yourself you're pregnant!

When I was younger, I messed around with a boy. With our clothes ON. And I was so silly and SO convinced I was pregnant. I got morning sickness, I got cramps, I missed my period... all from worrying!

So calm down, get a test. And even if you ARE pregnant.. stay calm, you're NOT pathetic and there is nothing bad or wrong with you!
