Hello, I had sex last August 29 and 30. I took an Emergency contraceptive within 24 hours. My "period" came on Sept 10 but it only lasted for about 12 hours them it continued on the sept 11 and lasted till sept 12. It was a little heavy. This month, my period came last Oct 8 and stopped on Oct 9. TODAY, Oct 10, I had a drop of blood on my panty liner. I'm not sure about the color but it was already brown when I saw it, I don't know if that is the actual color when it came out. I also have symptoms like acne and bloating, but that is normal around the time that I'm supposed to get my period. I did not get cramps this month so my "period" came as a surprise and it is also a few days early. Myperiod is irregular, I can only tell when it's about time when I experience I get acne, become bloated, and get crams (usually a day or 3 days Before my period). I also sometime vomit but I'm pretty sure that that is because of my hyperacidity since it always happens to me, usually when burping. I'm also stressed out lately and I changed my diet plus I've been doing a little exercise lately. Am I pregnant or is this just due to my chanhe of lifestyle?
