brown discharge anyone else?

tina

so a couple weeks ago i had an orgasm(by myself) and afterwards i got a really bad cramp, then couple days after started spotting light pink discharge that came out alot when i went number 2 or pushed down hard. Now for the past week ive had brown discharge like tobacco brown enough where i have to wear a liner. No cramps and still have symtoms more symptoms now actually. Is this a misscariage? I dont have a doc appointmnt until june 2nd i am now 7 weeks and 2 days. is this happening to anyone else ??
