Odd symptoms for me

Courtney • I'm a stay at home mom and currently working towards my degree in nursing.
This is my second pregnancy and I had to be induced with my first. I didn't experience any natural labor pains including Braxton hicks. (I say natural as in they occurred without medication.)
I'm 29+5
My issue is this morning I had peed and everything was normal. Went again an hour or two later. Way more discharge than normal with a chunk of something the size of an eraser top. I figured it was strange, but maybe coagulated discharge. Went on a walk with my son and dog and got the really annoying icky feeling cramps you get before you start your period. Not intense, but constant, very annoying and slightly painful. Had a normal bowel movement and still had the cramping. Drank water and still had it. Laying on my side did relieve the pain, but I still feel it lingering like it would come back if I walked around again. I have a toddler and dinner to make so I will have to walk.
Discharge is a pale yellow, it has been for awhile. Had a pelvic exam at my 28 week appointment for it and was negative for any infections.
Baby is active as usual.
If I call my hospital they will tell me to come in no matter what. I don't feel like going in if this is something normal. Every pregnancy is different, so what are your opinions?
