Baby dropping at 34 weeks, should I worry?

Kirsten • 3rd babe coming March 2022

Hey all I am a FTM and just had my 34 week appointment. I measured small (I have always been right on target) and I have been having some pelvic pressure so they think the baby has dropped. They are having me come in for an U/S next week. Should I be concerned? I didn't really get a whole lot of answers, just to stay hydrated and monitor if I have any contractions.
