Does anyone have experience of this. I have a new sexual partner but last 2 times I have an excessive bleeding, truely horrible. Of course I will be calling GP on Monday but have all weekend to worry about this. First time was without a problem, then I had contraception injection and thought might have been the cause but happened again last night. ( no bleeding in 2 weeks until after sex last night) I feel really embarrassed, not really very good to have this with someone new, any ideas what this could be.
