7 weeks, red blood

Had 2 weeks of implantation bleeding, (confirmed at the EPU after all being well at an early scan) then I’ve just gone 8 days with no bleeding at all.

We had sex twice on Sunday, then I’ve just had a gush of red blood (Tuesday night/7 weeks today). Could it be coincidence that it’s started again, sex somehow causing it, or do you reckon it’s game over?

I have a scan in the morning, but would just like to hear your experiences of this please so that I can sleep tonight!

Tired of this bleeding stress now!
