Oraquick (2nd Generation) OR Third / Fourth Generation Tests?

I am female, I had one exposure exactly 30 days ago, (4 weeks) unprotected vaginal intercourse with a man of unknown status. I took an Oraquick in-home HIV test on day 23 then again on day 30 and both come out negative. The symptoms I have had are excessive urination and a rash on upper arm. So of course I started freaking out. I plan on taking more on week 6, 9, and 13. You can say I'm obsessive. Any who, how accurate are the Oraquick oral swab HIV test at 4 weeks post exposure. I hear many people say its nearly 90 to 95 percent accurate by this time, however are they referring to a third and fourth generation HIV test, because as you know Oraquick is only a SECOND generation, so does these statistics refer to the Oraquick test or not? When will antibodies be detected at the earliest for an Oraquick HIV test? Has anyone tested neg on an Oraquick oral swab HIV test at three and four weeks then later tested positive on a blood test or any other test?
