Should I go for another std and HIV test?

I have not been ually active for a while now. I went a couple of weeks ago, after my bf and I had broken up, to the health department to get an STD and HIV test. It had been right at 2 months after he and I had . All of my results came back negative including HIV. I have researched that HIV takes the longest (usually 3 months) to test for because you have to develop antibodies. Do you think the results were pretty accurate or do you think I needed to have waited another month?
