What should I do?

I’m 23 weeks pregnant. Last night I got super sick, vomiting and reverse constipation sick (tmi sorry) I’m not sure if I just ate something bad or too much but I got really horrible cramps that radiated around my back as well. I also felt like I was constantly peeing? After I was finally done I laid down on my left side and started feeling much better. Fast forward to today, I haven’t felt my son since before being sick last night. I’m assuming he’s just resting from constantly being contracted in there from me being sick, but I’m a worry wart. I’ve tried juice and water but I still haven’t felt him, is there anything else I should be doing?
