Loss of mucus plug 14 weeks

So I’m really worried that I’ve lost a part of my mucus plug, I’m 14 weeks so I know it can happen and it generally regenerates but I know sometimes if my cervix is opening I might be put on pelvic rest and given progesterone. I want to get in touch with my midwife/birthing centre to maybe get a check up if they think necessary but the non-urgent queries number is closed for the day and I’m just not sure whether it’s worth calling the number I’ve got for urgent concerns as I have no idea how urgent it is!

If any of you have experienced this please tell me what you did and how it turned out! Thank you
