💩 help

I’m 14 weeks today, and I am SO constipated. Like in tears, because my stomach hurts so unbelievably bad. And throwing up because of the pain. I do miralax a few times a week, but this is the worst I’ve ever been. I feel like I have to go, but when I sit down absolutely nothing. Just constant cramps and pain. Anyone know any quick remedies? I’ll try anything at this point!
