Ouch guys I need advice.

Samantha • aprilbaby2017
Having really sharp pains on my left side. From belly button to the middle of my back. I think it's just has constipation and gas and I have an ultrasound tm so I'm not too worried but it's really painful and I was wondering what you guys used to make you go poo. Or if anything else could cause this. I'm 12 weeks 2 days btw
