Please help! Rant!!!

So I'm officially DONE with being pregnant. I'm 39 weeks 3 days and I seriously can't take it anymore. I love my baby girl but the pains I'm having are really starting to get to me and drive me insane. My whole everything from belly button down is so sore and feels bruised. My vagina and cervix are constantly sore and have tons of shooting pains that take my breath away. I've been getting so many irregular contractions and then what feels like menstraul cramps in my back that will last for 30 minutes at a time and they are getting very painful. They happen randomly too. I get a lot of randome popping and cracking from my pelvis shifting. It hurts to walk because of the pressure from her being so low and all the round ligament pain. My nausea is killer and I have absolutely no motivation at all after my nesting phase. I already lost my mucus plug and on the 28th I was told I was 2-3cm dilated and 80% effaced. I'm so ready to have my baby girl but I can't seem to cope with all the changes my body is making right now. Is there any way to help things progress or help jump start labor? I'm miserable and in a lot of pain and discomfort please any tips or tricks would help me so much.
