Ok, My boyfriend and I had unprotected sex a couple times this last month. I am not on birth control- and haven't been. I am usually pretty regular and the thought doesn't cross my mind that I could be pregnant, and if it does, I start the next day. First and foremost, I am not unusually stressed. I am 3-5 days late if allowing for a period to start a couple days late. I am mildly obsessive compulsive, so I can't not know- I have taken 4 pregnancy tests, everyother day starting two days before I should have started. I quit taking them that obsessively, because I keep getting Negatives-- I just can't figure out if I'm not pregnant what it could be. I recently had my yearly exam so I know it is not STD or cervical problems. For the past two weeks I have had a lot of headaches, nausea, I keep feeling like I'm motion sick and I'm not moving, and the last two days my breasts have been more sensitive. I don't know what to do. Could I even be pregnant? I'm really not that stressed about it- just want a real answer. I feel like if I'm not then something is wrong with me...

If your period is late and you have had sex recently, yes, of course you could be pregnant. However, after 5 days, pregnancy hormones will not show up yet on a pregnancy test. Wait until your period is due next month, I suppose, and test again, or make an appointment with a doctor. If you don't wish to become pregnant, please make sure that you start to use contraception.
