What Is The Treatment For White Discharge From The Vagina?

I've been noticing white slimy stuff coming out of my vagina..I've heard its normal but it's been alot more since I had sex I was wondering if that is still normal..and also last night I had a little confrontation with my ex my stomach got rly upset I tried to sleep it off..it didn't go away in the morning it was actually worse, I had to sit on the bed and breath b4 standing up and a bit later I was bleeding. It wasn't alot of bleeding but still it worries me and keeps me thinking it could've been a miscarege..? After a while it got a little better but i still feel pain. Does that mean Im pregant..was pregnant or what???? 0-o?
