the first day of my period but the thing is i didnt have my period but i was suppose to, is that kind of like missing a birth control pill since i didnt take one that day? i took a pregnancy test and it was negative but i dont know if its too soon to take one. my next period is suppose to come the 15th of october should i wait to see if i get it or is there anyway i can find out for sure now since i have some signs of pregnancy,sore breasts, tired, bloated, hungry, abdominal pain and the overall feeling of being pregnant.
