Sharp stabbing abdominal pain

I'm not on my period it ended just over a week ago, my husband and I are faithful so it's not an std. They did an ultrasound and said my ovaries look good. So I'm baffled I'm having really bad pain in my ovaries and pain shooting up my cervix and they don't know why. It's mostly on my left side but right hurts too. It's sharp pain that's intermittent not constant... Can't get in to see the obgyn until the 22nd :/
