Hi, I had an exposure( protected sex condom slipped off ). Few weeks later i got a uninary tract infection . for 3 weeks I have and still been under antibiotics (levofloxacin,ciprofloxacin,clarithromycin,doxycycline and cefuroxime ) i went for an Hiv test 6 weeks after exposure and was negative. I once had extreme fatigue for a whole day during this medication.. My question is could these antibiotics delay immune response to Hiv and thus delay antibody production??? i read most HIV antibody production takes 4-6 weeks and sometimes upto 3 months
