Contractions vs. Poop cramps

Has anyone mistaken the two? The past few months I haven’t been the most regular in the bathroom situation. When I have to poop, the cramps are so intense I can barely walk. I read that the two can be a similar pain. I’m a first time mom and I guess I’m just wondering if the two feel similar? Just trying to get an idea of what contractions feel like. I know I’m not having contractions. Just curious on what to expect.
