40weeks+4days

Lost part of my mucus plug 4/5 Wednesday morning (EDD) since then nothing but inconsistent contractions, painful but tolerable.. today I just felt so much pain and discomfort on my lower back and thighs and pelvic pressure when I walk, stand up, lay down, over all basic day to day things, should I worry? Just wondering.. because I seem to feel like it should be normal this point on to feel this shitty.. Lol
