I am not positive about those things. They can sometimes cause an imbalance in your ph levels and make things worse. I personally use baby body wash for that area.
I heard that doucheing isn't good, but I think you can use cream. But if it's making you uncomfortable, you should ask you're doctor what you could use.
Good luck!
They aren't recommended during pregnancy. They wouldn't be harmful to the baby since they are external but because of hormones and the change inexternal flora it can definitely make you far more prone to developing yeast infections and the like.
Yeah, I still use mine faithfully! It makes me feel cleaner especially now being pregnant with all this discharge....
