Hello, I Had Sex With A Friend And The Condom

Hello,

I had sex with a friend and the condom broke, at the beginning of intercourse before we were both wet. We both realised immediately and we pushed each other away immediately. She claims she is negative but I know she is an escort and you never know these days. It happened 18 days ago. I have not had any symptoms and I am waiting for it to be 21 days for me to be tested. But I doubt the accuracy since it will be an antibody test.
