Sudden pressure on my cervix

In the night and again this evening i’ve felt sudden pressure on my cervix, almost like baby is headbutting it trying to get out 🫣 it’s a really sudden, short lived pain but definitely makes me brace/doubles me over for a split second. I assume this is normal? I forgot to ask my midwife today at my apt! She did say baby’s head seems just a little engaged so i wonder if it’s that? Also had horrendous hip/lower back/pelvic pain today like my bones are going to break.
