do i have hiv?

i have tested 4 times in total since i was last pressured into sex by a guy i know.

i took a test at 6 weeks, 10 weeks, 3 months, and 3.5 months. all negative

can i stop now? my doctor said i should wait 6 months but planned parenthood said i should stop since its been more than 3 months. What should i do :(
