Mucus plug

I’m 34 weeks. I have been losing pieces of my plug the last four days. I find decent sized pieces (20c piece size and bigger) at least four times a day. This is my third bub. It didn’t happen with the other two. I have called my OB and she has advised just to keep an eye on it and if any pain starts to go in. I live about three hours away so going in isn’t just a trip up the road. My bub is breech, and I’m due for a scheduled c-section in five weeks (Due to an accident damaging my pelvis when I was younger). My question is, have any of you had this and it hasn’t meant labor is close? I realise it can regenerate, but it is quite a fair amount and I guess that’s what concerns me. With bub being breech, the chances of me actually going into labor before the scheduled date is slim right? I worry because my partner is working away and I’m out of town on my own 😔😔
