Baby dropped???

Nazaray

So ever since hitting the second trimester I’ve had unbearable heartburn to the point that it’d either keep me up at night or make me vomit. But now that I am about 30-31 weeks it has magically disappeared, now being replaced with pelvic/hip and lower back pain. Could he have possibly dropped? My friend said she has slowly seen my stomach getting lower over the weeks but I don’t know

I inserted photos to maybe help. From 25,27 and 30weeks
