TMI blood tinged mucus plug

I've had small bits of mucus plug passing the past few days. 37 weeks tomorrow so didn't think anything of it really but just went to the bathroom and saw the smallest piece in the toilet that was bloody. 🤔 I haven't had a cervical exam recently and it's been weeks since I've had sex lol so can't think of any reason for there to be blood. been feeling crampy, especially in the lower back but again, chalked it up to normal pregnancy pains.

thoughts ladies?
