My girlfriend had her last period at the beginning of last month (the 5th I think but I could be wrong). We had sex roughly 2 weeks after that. We used a condom with spermicide and I finished outside o her. The only problem is that I feel I may have *** a little inside of her even though I pulled out and had to finish myself off. She says not to worry about anything and that she hasn't gotten any of the signs of pregnancy yet, but I'm just extremely worried. She has yet to get her period yet and I'm really worried. Could she be pregnant? What are the odds that she is pregnant? Am I really just worrying for nothing? Somebody please help, I'm really worried here.

ANY time you have sex there will always be some chance of pregnancy. At this point, it doesn't sound like her period is really even late yet. If she doesn't get it in the next week or so, then she should probably take a pregnancy test. She may also want to consider taking hormonal birth control in the future. That won't make pregnancy impossible, but using multiple forms of birth control will decrease the chances of pregnancy. But again, ANY time you have sex, even with birth control, there is ALWAYS some chance of pregnancy
