I'm 7+2 today and last week (I think i was 6+3) when we had sex I had some light bleeding afterwards. It was only when I wiped, and it was bright but quite light red - wouldn't really call it pink. There was nothing the next morning or days after.
Yesterday when we had sex I had the same thing again. I have read it can happen due to softening of cervix, and is nothing to worry about. However, it does freak me out a little...
Has anyone had the same thing at this stage, and does it stop?
