I need some help with this because I am confused.. im a 19 year old female, and I never missed my period. I have a pretty normal 32 day cycles, maybe a day off, but normal. I keep track of my period on tha My Days app on my phone, and it says my boyfriend and I had unprotected sex the day of ovulation. Lately I've been feeling really tired, sleeping the day away if I'm not at work. Eating a bit more, with a weird cheese fetish. I keep getting all these headaches, and feeling nauseous. One day I threw up twice, and I keep having diahreaah, I can't remember the last time I just had a b.m.. my lower back was aching before, and I keep getting these sharp rollar coaster type feelings in my lower stomach.plus I keep having these crazy dreams that feel so real, I wake up shaking... my period was suppose to start on the 31st of July, and it started the 27th. Usually my period is really heavy, with bad cramps, but its was moderatally heavy (with little clots), went to spotting (red with light brown tint). Stopped, and came back spotting (light orangish red, rustic red, brown) again. It's the 1st of August now, and I still see very light pinkish red and tinted brown, and I took a pregnancy test but it was negative... I don't know what's going on, but can SOMEONE please help me, I need some type of answers... please, could I be pregnant still?

There are hardly ever false positives, mostly false negatives. Wait a week take another test. Do it first thing in the morning first pee of the day. If you smoke don't if you drink don't. Getting some prenatals and taking them might not hurt things either. If the nest test says negative call your Dr. get advice. If the nest test says positive call you Dr. your going to be a mommy
