Was this my mucus plug?

Just wondering if anyone has had this problem?? Please advice is needed. So i had bleeding last monday was hospitalized for a week it tapered off went home friday was spotting a tad bit of dark brown saturday then sunday i had numbers 1-4… next day i had number 5 and another pic i couldn’t add cuz too many but it was a smaller amount of dark brown… then earlier the night of april 9th going into 10th i have #6…

Doctors have scheduled a referral to a specialist to get better screening images of my placenta… but i’m just so terrified my baby will come early.

His HR is fine he is still active… has been head down for a few weeks… but my cervix seems to be closed according to doctor…. She didn’t feel with her fingers but looked in there said it seems to be high and closed?…

Just wondering if anyone has had a similar experience?? I know i need to wait for the specialist but its been a week of bleeding.. thinking its fine and over cuz i got treated for bv & now this… i feel so lost and confused because i didn’t have this problem with my first.
