I am pretty positive that I am not pregnant. But my period is late than usual. I think last time I had my period was 26th of June. Since my period is pretty normal, it should be here any time soon. My breasts are really heavy and warm. It happens whenever I am about to have period. But I am getting confused. My boyfriend and I had a protected sex and pretty positive that condoms didn t break. I am wondering my delayed period is due to having too much sex, since we haven t seen each other for a while. We had 3 sex per day for a week. Mine was hurting at the end but then I thought it felt normal after just taking a break. Can having too much sex at a time could delay my period? I ve been stressing out so much. I took 3 pregnancy tests so far, and all came negative. Two I took before my expected period date and one I took on my expected period date. Any advise would really appreciated. Thank you!
