Well ive heard breast soreness can occur from pregnancy as soon as 2 weeks, and so can the spotting (implantation bleeding) but other symptoms of pregnancy would not be felt this early so its probably all in your head. Either way u have to wait till ur period is late, before you can test. How old r you?? If your not pregnant, which im doubting ya are, but u could be, if ur not tho.. I reccomend getting on birth control? Condoms definitly arent 100% anyhow~
