Pulled Muscles?

Sam • 👶🏻 Sept ‘16 / 👶🏻 May ‘19
I woke up today feeling like I did a thousand crunches and pulled my lower abs/groin/upper thighs. Haven't done anything out of the ordinary though. Is this something that happens as baby drops? Because my little dude is definitely lower and I've been having quite a few BH today (nothing worth calling the doc about).
