I’m Not Sure

I had sex multiple times while I was ovulating. Unprotected sex. Then I continued to have unprotected sex up until 4 days ago. I was supposed to get my period yesterday. I didn’t. My breasts started to hurt 2 days ago, I have been cramping but, I got 2 negative test results. I’m thinkin it may be to early to show. I’m also hoping that my period is just late. (If I struck a nerve with anyone I’m sorry)
