First time

I’m 35 weeks, I started getting brown discharge about 4 days ago and I’ve been getting pains all in my back and tightening at the top of my belly and all my belly will go hard after. yesterday I had a warm bath but whilst I was in the bath brown jelly and little pink dots started to appear in the water, after I was fine for 10 minutes and then the pains came back stronger and been getting more uncomfortable and more painful ever since. I’ve been waking up in the middle of the night and early hours in the morning for the past 2 days because the pains get stronger. I’ve tried hot water bottle and heating pads and took so much paracetamol but nothing seems to work or help at least.

Last night I started randomly being sick and the discomfort began to get worse. This morning I’ve woken up to go to the toilet and there is a lot of clear sticky discharge, I’m currently in a lot of pain and can barely move every so often I get shooting pains up my legs and in my vagina ( tmi) I have no idea what to do!?
