Not sure what to do..

Hey ladies!

So I am currently 28 weeks 1 day pregnant first time mom and I think that I've been loosing my mucus plug the past 2-3 days.. Today especially I've noticed that every the I go pee when I wipe i have stringy yellowy green tinged mucusy looking stuff on the toilet paper.. I've also been having some mild pains in my lower uterus area and sometimes I have pressure down there.. I'm not sire whether I should go to the hospital and get checked or just wait it out.. I'm scared if I do wait that something will happen to my baby..

I would REALLY appreciate any advice to either help ease my mind or help me with what to do.

Thanks in advance!
