Have I dropped??

Sa

So I am 35 + 4 and my baby boy has been breech for several weeks. This morning I woke up and feel so much relief and like I can actually breath again and my babies movements are much softer. I can also suck in my stomach which I haven’t been able to do in months! Could it be possible that he flipped and/or dropped? First 2 pictures are today and the rest are last week
