I have ben having neckaches, and small backache, nasia, weak hands and feeling fatigue latly, am scared that i might be pregnant, because i had sex on the 23. of february, with the so called pull out method. and aprocmently 3-4 days after that i got my period. i havent missed my period for this month yet, and my period usualy comes at the end of the month og in the begining of the next month. am very scared that i might be pregnant, some people talk about implantation bleeding, wish made me unsure it was my period. i feel a slight stomach cramp and have be feeling bloated lately. am not sure if these are signs of my next period coming or if am pregnant. am obssed with reading about pregnancy and all of these syptoms scared me even more.
