Weird air bubble


Roughly 4 weeks ago I was positive for chlymydia I took a weeks course of doxycycline. I’m waiting 6 weeks to retest but I have had heavy thick discharge and a sensation that I can only describe as a air bubble or uncomfortable feeling in my vagina is this symptoms for chlymydia again? I have had no more unprotected sex could my previous antibiotics not have worked??? @Dr_Paula @Drew_WD
