stomach pains

Amber
I've had sharp pains around my right ovary area (I think that's what is there). 
They started around feb 25th, my period was due march 1st but didn't come come until march 9th and was really light and only 4 days instead of 6. Sometimes they're sharp, when I'm sitting or laying down it's more of a throbbing pain and I'm really nauseous in the mornings and nights and I get lower back pain along with it. I've also been really emotional the last 2 weeks and my face has broken out really bad this week. 
I went to the dr 4 days ago and because I had a negative home test she doesn't think I'm pregnant and ordered a cat scan to figure out what the problem is. 
Has anyone had similar pains and what was it? I'm driving myself crazy googling different options..
