When DD1 engaged it felt like there was a bowling ball sitting on the top of my vagina. I waddled like i was trying to hold it between my thighs. she engaged at about 35 weeks but was back to back so the engagement never triggered labour and i ended up going 2 weeks overdue.
DD2 engaged and then disengaged repeatedly from about 30 weeks. felt the same. a bloody great bowling ball.
Same as entwife and I'm experiencing it more now (39 weeks +1). When my baby dropped at 33 weeks I also had period type pains and the MW said this was probably down to baby's head moving down and stretching things. It makes me want the toilet non stop now!
