38 weeks 6 days - pelvis pain

Heyyyy! So I'm 38 weeks 6 days and I'm having the worst pelvis pain ever 😫 couple days ago I was taking a walk which my husband and I normally do but this time I almost didn't make it home it hurt soooooo bad .. feels like I pulled a muscle ☹️ and when I'm laying down and switch positions I hear a cracking noise 😳 I had an appt yesterday and was told it's because her head is on my pelvis and that she needs to be under my pelvis to get labor started 🤦🏽‍♀️ anyone else experiencing this or experienced this before?? Sn: I still haven't lost my mucus plug or dilated any 😭
