Hello I share your concern. Watery discharge with pain in lower abdomen might be related to Infection of inflammation of the urogenital tract or pelvic inflammatory disease. In my opinion you should go for few investigation like blood for hemoglobin, CBC, ESR, blood sugar and urine culture, vaginal swab culture or an ultrasound pelvis to establish a diagnosis and accordingly further course of action. Meanwhile maintain good hygiene, you can take mafenemic acid with antiacidity medicines like pantoprazole or ranitidine group of drugs for pain relief. Hot water bath will definitely help you. Hope I could answer your question, please feel free to ask for follow up question, I will galdly answer you. Best wishes
