My period was scheduled to start in 5 days, but bc my s/o and I had AMAZING sex, it started early. It was GREAT sex. He actually went alittle harder than he usually does and I took all of it instead of running like I usually do. My cramps are AWFUL. Like they usually don't hurt this much. I took 1 Tylenol extra strength I am and 1 Tylenol p.m. The regular period pain went away, but one side of my pelvis still hurts... Idk if it's from the rough sex or what... Also, there was dry blood along with my menstral blood... I have never had that before.. Is this normal? We didn't use a condom, and I am kinda scared that I might have an std... Could it be std? After the sex was over, my vagina BURNED. Like it doesn't anymore, but it did for awhile.
