Accuracy of 4th Gen HIV test

I am a female who had unprotected vaginal sex with a male all of January and one day in the beginning of February. My last exposure was February 7th. My first exposure was January 2nd. There were exposures in between (all with the same guy).

I had three 4th generation tests done (out of panic). Long story short, I had an assault experience a year ago where I had a huge HIV scare and now I’m slightly paranoid. This is the first person I’ve had sex with since.

The three 4th gen tests were on Feb 17th, Feb 26th, and March 22nd. All were non-reactive.

The test I took on March 22nd was 43 days after my last exposure. Is this accurate? Did I wait long enough?
