The first pregnancy I always have that. Seen a doc and took medication like those insert one but it still came back. But my gynae only mentioned oh there is discharge and then the convo ends there. Hahaha
The doctor prescribed me oral antibiotics after the pessary didn’t work. I think it was called Climadan. Were you prescribed that too?
