Dude, if both test came back negative, stop sweating. Stress most definately plays a major role in if periods are late or sometimes they are missed totally! Is she on the pill and are you using protection? Being on hte pill takes a toll on ones body as well. Everyone has different issues with their own body and month to month they may be different. Keep me posted!

Uhh she is not on the pill and we do have safe sex most of the time. Occasionally we don't, but when we don't I don't even get near the point to where I ejaculate. It just is basically making out while inside of her (if you know what I mean). She has been very stressed and she put on some weight before christmas and I know that can play a factor during the menstral cycle. Thank you for the reply

Lots of stuff can mess with a girl's period.
Weight gain, weight loss, stress, disease, a change in birth control, and, of course, pregnancy (im sure there are others, I just can't think.)
she's probably not pregnant, i'm guessing she's about my age
(i'm 17) and my friends and I have noticed that none of our cycles are really all that regular; they change a lot. If she's having cramps and stuff, then she's probably okay. If you're very very worried, wait a little longer and take another pregnancy test. Watch out though--different ones have different sensitivity levels, and since she just missed her period, get a really sensitive one. These are the most sensitive ones--the lower the lowest hcg (the hormone that all pregnant women have, it's given off by the placenta, I think), the better the test.

or, you could go to a clinic (planned parenthood, for example) (you can find them online, just google "planned parenthood") and get either a blood or a urine test. Her period's only a few days late, and the odds are her cycle's just changed. If she doesn't get it in a few weeks though, make sure to take another test and if it's still negative, take her to a doctor.

Note: always wear a condom!!!! Even if you dont ejaculate in her, you secrete pre-ejaculate, which has semen in it!! You could get her pregnant by doing this, it's a long shot but it can happen!! Sorry for all the exclamation marks, just wanted to let you know. :)

you sound like an awesome guy. Keep it up. Hope this helps!

I don't know if youre still stressing about this, probably not at this point- but maybe this will help someone else, but I went through the same thing with my period and the same kind of sexual situation you desribed. The only difference was I had lost weight. You would be so suprised how much this can mess up ones cycle. But chances are, if you don't blow it in a girl, she wont get pregnant. (but never, ever take the chance haha)

I forgot to tell you this--pregnancy tests don't detect pregnancy until around the missed period. Some girls just have very little of the hormones during early pregnancy. So if you take one really early, it might appear negative.
