Has this happened to anyone else?

Well I lety husband have a quicky last night cause I wasn't in the mood at all. So he did his thing (wasn't rough or anything and finished inside) well this morning I had gone to the bathroom and there was about a nickel size discharge when I wiped and there was brown mixed in with it. My first appointment isn't until the 14. 
I don't know whether it's in my head or not but after I had gone to the bathroom I'm getting weird feelings or cramps in my one ovary area.
Should I be worried and try to get a sooner appointment or is this normal?
Withy first daughter I bled like crazy when I was 30 wks after sex but never had any other problems
