Okay so here is my story. My cycle in May was the 6th-8th and I have a 26 day cycle, I use a calculator for my ovulation days and it says my ovulation days were May 15-20th, I had sex with my boy friend on the 17th-19th, 2 times it was unprotected, on the 20th of May I started spotting some pink and on the 21st of May I got a medium size wet spot of blood but after that no more bleeding, about a week later I started noticing that I could not lay on my stomach anymore because I had small pains every time I laid on it and my breast were way too sore to lay on too, I started felling an upset stomach come on through out the day but not every day, my back hurt and I had small cramps in the lower part of my stomach. I waited 3 days before my period was supposed to start (6-1-13) to take an HPT and it came out negative. I started spotting on 5/31/13 and then a light bleed on 6/1/13 then my normal heavy on 6/2/13, I usually I only last three days but I didnt end until 6/3/13 and now I have a light brown discharge, I still can not lay on my stomach, the little pains are still there, the nausea seems worse then before just no vomitting, my breast are ichy but not as tender, and my appitite has change a bit meaning I eat more the usual and I am getting small headaches. So is there any chance I could be pregnant or is it just late PMS symptoms....
