I had sex 6 days ago and just started to get a slight discharge. I have abdominal pain and back pain and nausea. I am expecting my period in abou a week, but was wondering whether the discharge is a sign of pregnancy or ovulation. My concern is that it is not as much as my normal ovulation discharge, but is quite similar, and was wondering if sex messed that up or if I may be pregnant.

If you had sex during your fertile window, then it's possible you could be pregnant. The trouble is, it's almost impossible to tell, as things like discharge and back pain etc can be caused by so many things.

Some women do feel implantation, as a sharp cramp like pain, accompanied by sudden exhaustion for a couple of hours. But many women feel absolutely nothing.

I think you'll just have to wait it out and do a pregnancy test at the right time.
