Could my hysterectomy be causing severe pain and spotting during intercourse?

Hi, I had a hysterectomy almost 3 years ago due to endometriosis and andometriosis. I still have 1 ovary and I have been doing well for the most part since surgery. Recently (within 2 months) I have started having severe pain with intercourse and spotting afterwards. I am very scared and when I called to ask the Dr about it they called me back with an appointment in about 10 mins. I don't see them for another 2 weeks but I am concerned at the quickness at getting me in. Could it be something really bad or should I stop worrying?
