yeast infection- 27w1d.

HELP!!! I have tried everything. My ob told me they dont prescribe anything for it anymore (I dont remember why)... I have tried monistat, different soaps, EVEN my daughters soap!! I've tried sleeping with no panties on to air out... NOTHING! I'm uncomfortable, itchy, having to change my panties like twice a day bc of the discharge😫😫😫 this has been a constant on and off thing since about 10 weeks and I am literally about to go crazy bc at this point its causing pressure pains in my VAGINA and this infection just will not go away... please help y'all.
