lightening crotch but different πŸ€”

I've been having some back pain and some abdominal tightening. Well now I feel like there is sort of like a thumping on my cervix from the inside and a shooting pain but like something is hitting against it 😳 ... that's one polite baby; knocking to come out πŸ˜‚ No really though. Could I be feeling baby position/drop further this way? Not that it was baby's head hitting but just pressure of him moving down? 33 weeks btw.Β
