Remarkable. You've managed to discern what doesn't defy the laws of basic physics and anatomy during labor.
Your observation that something 'doesn't belong' is... accurate. One would hope such a fundamental concept wouldn't require extensive contemplation.
- Concept Verification: Let's review, for those who might find themselves momentarily bewildered by the concept of gravity. During the second stage – yes, the one where the fetus actually comes out – one would expect the fetal head to... move down. This rather inconvenient descent then causes delightful symptoms like increased bloody show and a rather pronounced perineal bulging. And naturally, with a head pressing on the rectum, a delightful urge to defecate manifests. Now, here's where it gets truly complex: if something is moving down, the highest point, the fundal height, has absolutely no business migrating upwards. Unless, of course, we're discussing a uterine hemorrhage, which I assure you, is an entirely different (and far more pressing) problem that you certainly should be able to differentiate.
