It does look like part of it, you can loose it and your body regenerates it, if your having tightenings contact triage they might want to see you x
It could potentially be your mucus plug, mine had a steak of bloods (looked kinda like a vein) but definitely worth getting checked out with the tightenings too it’s the only real way to put your mind at ease anyway!
I loose mine all the time! Have with all my pregnancies and birthed all babies full term 🤍
This is reasurring !! Thank you !!
I would say if you are high risk feeling tightening and unsure on discharge you should be ringing your midwife or PAU ❤️
