Advice please

I was assaulted on April 8- three days before my ovulation day. He didn’t use a condom and I’m not on bc.

I tested 9 days later for pregnancy when I went to health services on campus and it came neg (could have been because it was too soon)

I also tested on April 19 (11 days later) because I had surgery and it was part of procedure - also came negative

And I finally took two yesterday (16 days after the incident-I’m supposed to get my period today) and they both came negative.

I’ve also sent my tests to the lab for std’s-haven’t back yet

Do you think I’m fine regarding pregnancy?
