Hi, lately ive been getting a lot of discharge, especially when i have sex. And after ive had sex it looks sort of pinkish which could be blood but not like im on my periods. i thought it may be a water infection that still hasnt gone away as i had one a couple of weeks ago and was prescribed 3 days worth of antibiotics which had to be taken twice a day but when it didnt go away they prescribed me with 3 days worth of stronger ones which i had to take 4 times a day. im not sure if this could be the problem or something totally different?
