Weird question but I just have the curiosity

So this is my 5 pregnancy, my first pregnancy was a spontaneous abortion 😔, my second pregnancy was the only one I can say I loose my mucus plug, had a little bloody show and my water broke at home. Since my water had broken early in the morning and it was close to 1 pm and my contractions were not moving as expected, plus the baby got breech last minute they had to do a emergency csection, for my second, and third nothing happened at all no mucus plug and no water breaking and no dilatation happening the doctor had all ready schedule me for c sections. For my 4th pregnancy contractions were crazy, went in for my 38 weeks appt they didn’t an nst contractions were consistent and then they check me and I was in what they consider early labor. Was sent to l&b where they kept me for couple of Hours and when the doctor check me again there was some bloody show and I was at 1 cm and 60% efface and baby at at -3 engaged. since I had c sections in the past they did a csection that day.

Now with this pregnancy I have been having bad contractions on and off but when I go in they seemed to control themselves and or stop 🤦🏻‍♀️. Now yesterday I went To run some errands with the family and I am not sure if was all the walking plus having intercourse at night but I have been feeling a lot of pressure down there 👇🏻 and weird sensation like i am getting my period or something. No big gush or bloody show yet but at times I feel alot of cramping and contractions come and go.

How would I feel if i was to loose my mucus plug? Any feeling or sensation ? 🤷‍♀️ sorry I just don’t know what it is to loose it mucus plus?
