Baby dropped..

My baby dropped yesterday. I had a little discomfort and some weird feelings in the night and the a sudden feeling of being able to breath again & my bump was noticeably lower and I didn't have the massive full feeling ive had throughout! I took pics but I was naked so don't wanna post them lol 🙈 .. Anyway, tonight ive been experiencing what I think is indigestion/heartburn & now my bump feels as if it's no longer dropped! Can this happen?! I'm in so much discomfort it's unreal. I don't know what's happening. I'm 36+3w pregnant. Someone please help 😥
