Morning sickness back?

Keilah
I was lucky to have morning sickness leave at 11 weeks, at 15 weeks I felt fabulous and almost not Pg at all. Now at 22 weeks it seems like my body isn't happy at all, I have a mix of reflux, naseua, and general tiredness. I feel like I've been lucky to have a reprieve but is this normal.  Wondering if it's GD symptoms cropping up early.
