me and my boyfriend has sex three times in a row( used a condom all three times) i had my period a couple days after that and it was like any other period. two weeks after my period i began having morning sickness, diziness, and abdominal pain. this brown redish substance came out from down there and lasted for about a week. now this usually happens right before my period or right after it and it doesnt last that long. so its never been 2 weeks after having my period. i dont know if i might be pregnant because of having sex three times in a row.(there is always that .1% even if using a condom) my period is supposed 2 be on the first week of october. today is sept 26. please hlp im extremely worried
