Had unprotected vaginal sex with a female yesterday 3/10 at around 10am, before we got into it she showed me her most recent test results (12/28/19) as did I (1/3/20), immediately after I experienced a panic attack and she felt how worried I was and tried to calm me down. We ended up going to a clinic together where she got tested with the rapid test (not sure what gen), her test result was negative. now I know there is a window period of course and she swears up and down the last time she had intercourse was 3 weeks ago with a partner she’s been dealing with for 2 years+ up until recently and he also got tested recently. Currently I’m freaking out and considering going to the ER for PEP. Please advise
