Alright well me and my boyfriend had unprotected sex on october 1, 2, and 3 and I was supose to get my period on the 15th, but it still hasn't come, so on the 16th I took a test and it came up negative. Well today after me and my boyfriend had sex I felt a really bad pain in my lower stomach, then a couple hours later I went to go to the bathroom and there was a lot of blood all over

But I haven't been bleeding since, so its not like I got my period or anything...So waht do you think has happened? Did I have a miscariage or what? Thanks
