Mucus plug came out after sex (31 weeks)

KY

If my mucus plug came out at 31 weeks should I let my doctor know even if I’m not having contractions and I feel fine.

I know it can regenerate but I read that the only time I should bother my doctor about it is if it happens before 37 weeks.

This is my 3rd baby so I’ve never had it come out this early..

husbands fault.. 🤦🏻‍♀️
