What would you do.???

So I went to the hospital yesterday for contractions, they monitored me for 4 hours and then the on call doctor sent me home because my contractions weren’t strong enough. When I went in I was dilated to 2 and then when I got checked before I left I was at a 3. I am still having the contractions and they are about the same as yesterday but I lost my mucus plug yesterday. I’ll be 39 weeks tomorrow. My thing is I don’t want to go back if they aren’t going to keep me!
