Post menopause bleeding

Hi,

I'm looking for some advice. I'm 49 and went through the menopause when I was just 44. I've not had a period now for 2 years and this past week I've been spotting. Its been mostly light but a mix of dark red and brown. I've also been getting pain in my lower right right side and lower right back. Also intercourse hurts. I've booked to see my gp tomorrow but not sure what to ask. 

Thanks in advance
