I already have a son but want to find out if i am maybe over reacting.....my son was away on vacation and my boyfriend and i had sex all the time. My son got home and shortly after i started what i thought was my period only if was half as short and very spotty. i carried on like usual. We have only had sex a couple times after my "period". We almost never use protection we just try to be careful. The reason for my concern it that i have started to have some signs...nausea, headaches, cravings, sore boobs and so on. my period is like two weeks away and i don't know if i should be worried. I took a pregnacy test and it was negative. Pregnant or over reacting???
