COULD BE A YEAST INFECTION. GO SEE YOUR DR HUN !
U must go see your doctor. Same thing happen to me. My doc gave me meds to take for two weeks. It cleared up just find. Although I still swall sometime after sitting all day or sex.
Call your ob so they can find out what kind of infection it is. If its just a yeast infection you can use monistat safely. Eating yogurt daily and reducing the amount of bread you eat is supposed to help prevent future yeast infections.
No it's normal actually, it could be yeast or BV but you need to get tested and treated for them cause they can harm you.
You should ask your Dr. And no I doubt it could hurt your baby unless its a type of std.
