Go in and get checked. It doesn't matter how many people post that it sounds like everything is fine, you will still sit and worry, tis the way of the pregnant woman . Best just to go get seen then you can come home and relax.
Hi, I'm also 37 weeks & am convinced mine is trying to break one of my ribs. If the pain is still there of course you should have the midwife check it out. The MWs always say to call if there are any changes to the bumps normal behaviour. Anyway thw stress of worrying about it can't be good for either of you. Let us know how it goes.
