Sleep issues

I don't know what to do anymore. My daughter was doing well sleeping in her own room in her crib and then all the sudden a switch flipped and now she will not sleep unless she is touching me. Some nights I can maybe get her in her crib for 1-2 hours but after that she wakes up and there is no getting her back to sleep unless she's in our bed. I can have her completely asleep in my arms rocking her but the moment I stand up to put her in her crib she pops up and starts crying. I've tried to let her cry it out but she also has randomly starting pooping at night again so I don't feel comfortable not going in and checking on her to make sure her diaper is clean. I'm pregnant and exhausted and my husband works long hours at his company when he's not on shift at the fire station, the easiest/fastest thing to do is let her sleep with us. My sleep suffers because I'm constantly either waking up to check on her and make sure she isn't too close to our pillows or I'm getting up to pee. I just want my bed and sanity back. 😭

Any advice is appreciated but I also just wanted to whine about it a little.
