I'm a 20 year old female and have always had regular periods, ever since I started at 10. My boyfriend and I have had unprotected sex 3 times, and I am a month late on my period. I've taken two pregnancy test, both negative. Could I still be pregnant? Am I too early to show up on a test? I need some answers so bad! Please respond and give me some help..

Being a month late, your HPT should be giving an accurate result.

You should probably call your doctor to arrange for a blood test to confirm with 100% certainty.
