Ok so fiancée and I had sex like 3 times this month... I got the flu early this month and was on antibiotics which caused a urinary tract infection... Im in my last year of college and had to study for some hard finals was super stressed, slept probably 7 hours at most in a span of 3 days (not good for my health I know)... we wouldn't mind getting pregnant its just inconvenient... but is there a possibility? Im only late like 3 days not that my period is regular but it usually comes around the same time... some people say its stress and I took a pregnancy test that came out nagative but still a bit concerned

Yes, it can be all of those things, basically time will tell.

No real way to tell

It sounds like stress... however take another pregnancy test in a week they say that 9 days after your missed period you will get the most accurate result. You could also go to a family planning and get pregnancy tested for real.

Did you use a method of B.C (condoms, the pill) ? If not then you will def have a higher chance that is pregnancy if you did its probably just stress... but you never know. If you are preganant and are planning to keep the baby, def keep up on it because you can't stress your body out for the first few months because you could miscarry, also you want to get on those prenatal vitamins asap.

Best of luck!

We used a condom

Then I would say that it is most likely stress. The odss are against you however you never know. I went 3 months without mine and swore I was pregnant but it ended up that I was just overstressed with school and life issues... it happens the more you stress the longer until you get your period so just calm down and wait. That's all you can do.
