Lost a big piece of mucus plug today

Envy

I’m only 17 weeks and 4 days but I’m measuring at 18 weeks and 2 days. I had just took a trip to the ER on Nov 5th for vaginal bleeding. They said the baby is fine but because I just had the bleeding 2 and a half weeks ago and now I lost part of my mucus plug they don’t want me doing anything strenuous. As far as they’re concerned everything is fine but man it’s scary to think about 🥲
