Heartburn after baby drops?

I'm pretty sure my boy dropped by now (36+5).... I had been carrying high and now it feels lower and I have been feeling pressure in my pelvis for over a week, with sharp pains, and generally changing there whole way I walk (much harder now).

But I'm still having terrible heartburn. Maybe even worse than before. All day and night, even drinking water is hard as I always feel full and acidy.

Is that possible that even after the drop my baby would be still pushing the stomach?
