It could be just heavier than normal discharge, or it might be related to the green stuff.
It's the green i'd be more worried about, and the fevers and stuff, i'm glad you are going to the doctor, you can't be too careful.
They'll probably ask you questions about your sex life, so if unless you can talk about that stuff very openly in front of your mum, I would not take her into the actual consultation with you- even if you are nervous going in. You have to be able to be absolutely open and honest with whatever they ask you- ok ?
I'm 27, married, and pregnant with my 2nd child and there is no way I could even mention sex with my mum in the room !!!!!!! She wouldn't care - i'm the one who'd be embarrased !!!!!
