what could this be?!!!

So I'm 29 weeks pregnant and I always get really sharp pains in my ribs.. like below my breast. It's not my abdomen but it's just my ribs. Sometimes when I breathe it gets even worse. I start to sweat really bad and I even throw up sometimes. It also seems to give me diarrhea (sorry tmi). What could this possibly be?? I used to only get it during the night but now I'm starting to get it in the day time too😟 taking a really hot shower sometimes seems to smooth it a little but not always. My doctors office is closed until Wednesday and I'm desperate. I don't want to go to the ER cause I don't know if my insurance will cover for something like this.
