Is it too early for baby to be dropping? (31+2)

Briana

The last 2-3 days I have had really bad lower back and abdominal pain, almost feels like round ligament pain but constant. I also have noticed I’m making much more frequent bathroom trips and my belly is noticeably lower. Dr has said she’s measuring about 2 weeks ahead in size (no change to due date 12/25/20). FTM here and I guess I’m just wondering if anyone has also already dropped or anyone has dropped this early in a previous pregnancy and if it’s something to be concerned about?
