It could also be a condition called bacterial vaginosis. Which can happen after a pH balance change since you had unprotected sex might be related. You have to see your doctor and get on some specific medications for that. Sometimes it can also start to cause an odor
Hi there. Well, it's odd for sure and most likely something hormonal could be going on. Yes, could be pregnancy related so take a test. Or it could be an imbalance such as producing too much progesterone. So, first take a pregnancy test and consult your doctor if positive for prenatal care or again, consult your doctor if negative to determine what is going on. good luck
