Belly starting to drop ever so slightly 🙌🏻

I think I’m in the beginning stages of my belly starting to drop. I’m 36 weeks and I noticed much less pressure on my lungs today and also kind of an “empty” space at the top of my uterus where my baby girl usually is. I have to press further down to find her. Here’s last week and this week. There’s not much difference at the bottom but the top looks somewhat different and that’s where the empty space is. I know it’s very, very slight but at this point I’m looking for any small sign that relief from the heartburn and shortness of breath is in sight! 😂
