Ok so i am pretty sure i lost my mucus plug yesterday and today i have really bad back pain that radiates from my tailbone all the way around to my pelvis along with sharp pains in my belly and private my due date is october 1st and dont see my ob till thursday and have a babyshower planned for this up coming saturday my mom is afraid i am going to go into labor before the babyshower cause my first was 21 inches and i am only 5'2 plus it doesnt help my 3 yr old climbing on top of me and rocking back and forth when i am laying down cause it hurts to stand or sit....my question is when you lost your mucus plug how long before you went into labor
