I had unprotected sex two weeks ago I have had really tender breasts, always feel like I'm going to be sick, and tired all the time for a little under a week and a half now thought I was pregnant but yesterday I got my period but it was two weeks early it is very light witch is not normal for me could I be pregnant

Probably not but go check with a doctor

It is possible, just a little early to tell, you will really need to wait till it is time for your period and if no regular period, do a HPT then.

Well usually not everyone's periods are on time, but I suggest for future reference you get on some sort of contreceptive because believe me when you become pregnant and you realise its not the right time it ruins your life weather you have the baby or not it sticks with you forever so be careful.
