Ay, mama, congrats on hitting 38 weeks! It's likely your mucus plug, especially after squatting, that kind of activity can definitely dislodge it faster. The good news is it doesn't mean labor is imminent; it just means your body is definitely moving towards labor, which at 38 weeks is totally normal and actually a good sign that things are progressing. Someone in my mum group said hers came out in bits over a few days before she actually went into labor, so don't panic if it's not a one-time thing. That said, if you start getting consistent contractions or any discomfort, definitely get checked by your OB, better safe than sorry, especially since timing matters at this stage. For now, rest up and keep an eye on any changes, but this is actually your body doing exactly what it should be doing!
