TMI 💩 question

For a couple of weeks now I’m going 2-3 days between poos. And when it finally happens it’s so painful that I think about stopping midway (though I know that will make it worse). And when it comes out it’s seriously shaped like a coke can... which explains why it’s so painful. Anyways, anyone else dealing with it? Any easy remedy? I have an OBGYN check up Thursday and might bring it up, but I’m so shy about these things
