Hi,
Welcome to ehealthforum,
The abdominal cramps due to infection can persist until the infection is completely cleared and the inflammation is under control. Vaginal infections can turn into PID anytime (time span can vary from few days to few months for the infection to travel up towards pelvic organs). Consider completing the treatment course prescribed even if other symptoms are under control. Drink plenty of water. Take adequate rest. Maintain healthy diet and lifestyle. Avoid vaginal douching, use of harsh soap or perfumes in the area. Use loose cotton undergarments and avoid tight fitting clothes. If you are sexually active, get your partner also treated simultaneously to prevent re-infection and avoid having intercourse while being on treatment course. Be in regular follow-up and monitoring of your treating gynecologist/obstetrician and report any unusual/abnormal/new symptoms immediately.
Take care.
