Hi, this month my period has been completely out of wack. I started spotting and light bleeding two days before my period was even supposed to start. It has been all brown, some days light, some days dark. It hsn"t been heavy at all and no cramps. I usally have terrible cramps.I began this last Sunday and it is now the next Monday. I am sexually without protection. I had sex everyday between my periods also. I have normal periods since i was 10 and i'm 17 now adn they last 3-5 noramlly. Any advice!? Please and thank you.
