Concerning?

I had a csection March 9th. It was my third so I pretty much know what’s normal and what’s not. Just a heads up, this is going to me TMI. I had my first bowel movement March 11th, and it was normal. Starting the 12th I developed diarrhea but didn’t think much of it. It has not let up since. It’s like water and just pours out of me at this point. My pee is literally orange and smells awful. No matter how much I drink it is not getting better and I do believe the diarrhea has dehydrated me. At my 2 week appointment I brought it up to my ob but he didn’t seem concerned, just said of it got worse take some of the counter meds, which I have. I’ve been having chills, the diarrhea is worse, and my pee output is decreasing and not even the urgent care will even began to tell me what’s wrong or what I can do. No one will even take blood just to make sure I don’t have something wrong. What can I take or do? Very worried, especially since it’s draining me and I feel lifeless sometimes, I can’t even get out of bed. It gets worse the longer I go.
