Okay so I'm not on birth control... I am five days late with my period, last time I was three days late and the time before that two. Seems to be irregular.. I have had cramps and feel like I'm going to get it but haven't. I have taken two tests and both have been negative. One I took two days after I think I should have gotten it and the other five days after I think I should have... I'm setting up a doctors appointment for next week but am really worried!
I'm not sure what to think or how worried I should be?

Ive had sex three times sense my last period, never has he released inside of me.'

Yes you could be pregnant. Those tests are not 100% accurate. Even if he wasn't trying to release inside of you, if ANYTHING got through before he pulled out, there is a chance.
