Yes it could be normal depending on her time of the month. Or just a general yeast infection, bv, etc
I had a ton of discharge out of no where. It was really odd for me. Turns out it was the chlamedia (sp) WH gave to me from his whore. Early on he made comments about her being loud in bed, I said she was faking. He said no, she was always wet. I screamed at him it was because of her fucking std dumbass! Sorry for the thought jam :/
Have you been tested? Has she? Even if she claims only ea, this would be a nice way for her to show commitment and understanding towards you. Health is not something to screw around with. How much can you really trust someone who has chosen to go behind your back? You can't.
