Thanks ladies! I'm just a little nervous.
Yes it does. The mucus plug is just a build of cervical secretions that 'plug' the cervix. Once you lose it the cervix continues to release these secretions and it can build up again. I lost mine at 27wks and have been on meds since to control my preterm labour, now 34wks, and my dr wasn't concerned at all because it most likely will have regenerated. Good luck!
Yes. It can replace itself.
