I had unprotected sex almost two weeks ago and all through the last two weeks also, and 2 days before I have started to get a really light pink mucus discharge when I clean myself from doing the toilet it doesn't be in my underwear and since I've not been on the pill for just over 2 weeks I assumed it was my period only it's not increasing in amount or colour if anything it is decreasing. I am tired all the time feeling sick most of the time my appetite has increased and I am needing the toilet a little more than usual too what could be wrong? Please reply as I'm confused and don't know what to do
