Of test,ultrasound etc. All gynae docter said everything is alright fluid must be you are ovulating, but pain is contant ,like I'm in period all the time ,since 5 months , but I knew something was wrong, so told docter to for ultrasound about that fluid ,then we found out after many months that I have excessive fluid in my pod and severe backpain , just completed my piptaz iv and yesterday had ultrasound, and found out only few fluid left in pod. Due to course of antibiotics im also facing vagina itchy and chunky discharge with all the symptoms above there. But im not feeling anychange , I still have same pain in my pelvic ,accompanied with nausea and low fever . What's happening, I have more one week of antibiotics course and also taking medicine for v ingection and preprobiotic, but why this pain is still contant ? My pod is already clearing.
