Did I have a miscarriage??

wh
Okay, I made a post about this before, but I only got one response, so I'm making it again. Back in October of 2015 I had unprotected sex on my high fertile day (he pulled out.) And a few weeks after my "period" (tbh idk what it was) came 14 days early. At first it was light blood, then it stopped, a few hours later, the blood would come out heavily. It went on like that for about 4 or 5 days then stopped. But beforehand I kept having to pee nonstop. Could I possibly have miscarried, or was it something else? Any type of help would be greatly appreciated. Thanks girls ❤
