N2L I#ve had this before and i never ended up fonding out what it was, thought the same things as you. the last time i had it was a few weeks postpartum, it went on its own, maybe it was mild thrush. I just put it down to irritation at the urethral opening.
Interesting Saff. I wondered if I had irritated it while applying thrush cream?? I am keeping up with the ural and cranberry capsules just in case.
