Hi I'm 18 years old and I lost my virginity maybe like a month ago and had unprotected sex, he didn't *** in me. But just a few days after having sex I've been having weird symptoms like headaches, nausea, I'm really bloated, I et dizzy, I'm always sleepy and moody, plus my period is a week late, I took a blood test 2 weeks ago and came out negative but I still have these symptoms I also get a white discharge and there's something weird with my taste buds because Ive been having a weird taste in my mouth that doesn't go away, can I be pregnant? I just don't know what's happening to my body...
