Moms of multiples: when did you drop with third baby?

So I’ve been having on and off Braxton Hicks for a few weeks, and yesterday I had light ones early in the morning then around 1:00 they got stronger and continued in decent strength until 6 then died down. They were regular but odd timing so I couldn’t tell if they were preterm contractions or not. But I was packing my bag for L&D when they started to calm down so I didn’t go in. This morning I woke up and baby was insanely low, like I looked in the mirror and was shocked. I know dropping isn’t always accurate, but since I’ve already had two babies I was thinking it might happen closer to labor, but between only being 32 weeks and the contractions I’m wondering if I should be concerned?
