I would still call labor and delivery for a second opinion, you dont want to go into labor without being sure if you have an infection or not.
I might go get checked just to make sure it's not something else like meconium. Best of luck!
I would call l&d. I was told any itching could be a sign of infection. Id call just to be sure. I didnt itch when I lost my plug. I actually just felt something goopy kinda drain out in a giant drip if that makes sense.
