Help! I am almost 34 weeks and I had some bloody mucus?

Tala

So last night it started off with a terrible terrible stomach ache then I started getting cramps along with it kinda like menstrual cramps and gas pains mixed but the pain would come and go and along with it my stomach would get super hard like contractions .. I thought it could just be that I ate something bad but I went to the bathroom twice and the stomach ache and cramping still continued but a tiny bit of mucus with blood tinted in it came out? Should I be worried at all??? I sure hope it’s not pre term labor! Does false labor hurt at all? Someone help me please I am waiting to hear back from my doctor and I have an appointment tomorrow should I wait till tomorrow or just to in today??
