I dropped at 37 after I hurt myself on accident
My first dropped around 32-34wks and my dr told me, I hadn't noticed. This one dropped around 28wks and I suddenly had a gap between my boobs and belly, had painful pressure down there, and they couldn't scan all of baby at 28wk scan because it was so low.
Im 33/34wks and ive recently dropped... like she Said you'll notice space and your belly hangs low
I'll be 38 weeks thursday and I still haven't dropped. I think it just depends on the baby. I know you'll feel "light" down there and there will be a noticeable space between your chest and belly :) and you'll probably get comments from other people!
