Cervix dropping?

We had sex to encourage the start of labor and it definitely felt different today. It’s been getting more and more uncomfortable each time (sorry hubs) but tonight I felt like I didn’t have much room for him.. is that a thing?? Could it mean my cervix might be dropping and getting ready for labor?

I have an appointment with my midwife tomorrow and might ask her to check my cervix finally. I’ll be 38 weeks Wednesday!
