High White Blood Cell Count

Mrs.

My husband and I had sex Sunday night and hours later I started having abdomen pain. It hurt really bad until 3pm Monday and has since subsided. There is still pain if I move quickly or my dog jumps on me.

Urine test came back negative for pregnancy but I was 9dpo monday. Waiting on blood test results done at 10dpo.

My wbc count came in at 15.3 monday.

Everything else in my blood/urine test looks good. The Dr. Isn't sure what is going on, said next step is a CT scan which will cost me 1k out of pocket.

Ideas?
