HORRIBLE CONSTIPATION!

So with my first pregnancy, I skated past the whole constipation train. Thought I'd have a similar experience this time around. NOPE!! I spent four hours in the bathroom with the worst pain I've ever felt in my life. Not even kidding. I didn't know stomach pain, gas, and cramps could hurt so bad. It was worse than labor and I had a particularly hard labor! My butt is so sore I can't sit. Please please tell me what I can do for this. Are any medications safe to take? I've left a message at my OB's office so hopefully I'll hear back soon. Laugh at my ass (pun completely intended) all you want, but for the love of all that is holy, pease give me some advice while you do it. Y'all. My poor butt. 😫😭
