I am pregnant. I have a yellowish/greenish vaginal discharge. I took neopenotran suppository for 7 days. The discharge though seemed to increase. On the 8th day, I had culture and sensitivity test and gram's stain test. I took clindamycin for 7 days while waiting for results. I'm still having scanty yellowish/greenish discharge, sometimes with a streak of fresh or old blood. Got the culture/sensitivity test and gram's stain test results after almost 3 weeks. "No growth after 3 days of incubation at 37 deg C." "No microorganism seen."
Why am I still having this discharge (although in much smaller amount)?
