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.
