Brown Discharge&Possible Pregnancy

[Yoshters]

Hi, I'm 20 years old and I got sexually active on March and my last day of sexual activities were on March 14 (I was already 2weeks late on my period). We used protection and he later ejaculated outside of my body but inside the condom. I finally got my period on March 28, then April 28 and I missed May and at Jun 13, I got a brown/black discharge for 5 days. I took 2 pregnancy tests, (1 at March and another in June) both testing Negative, yet I feel nauseous everyday, headaches, stomach aches, I always feel sick after every meal. Could I be pregnant? Or is bit stress? Lately I've been very stressed and constantly worrying about a possible pregnancy, since I am not ready to be a mom. I wish I would have waited til marriage so I don't have to be worrying about this. Or can it be something else? Thanks for taking the time to read. Sorry if its too long but thought I would fill in the details.

I don't think you are pregnant. I think you are just stressing yourself out. Try to relax.

Maybe make an appointment with an OB and get checked out....

Dont have unprotected sex if you dont want to get pregnant also maybe look into contreceptives? There are many forms of birth control out there. Either way I dont think you are pregnant you took a test it came back negative.. most women who are stressing a lot tend to be late on their period, doesnt necessarily mean you are pregnant.  So hope for the best and if you are late again take another preg test. If its negative start using contreceptives to avoid situations like these. Hope this helped :)
