Hyperemesis gravidarum help

I'm new to this whole HG thing. I didn't have it for my first 2 pregnancies but went to the ER with extreme vomiting and dehydration, and they "diagnosed" me with it. It was very bad and rough from 8-13 weeks then about 14-16 weeks it started to be manageable then seemed to disappear. I'm almost 24 weeks and I feel like every day I get more and more nausea again like when I was first pregnant and had to be sent to the ER. Every day it gets stronger is this normal of HG or has anyone else had this happen before? I'm not overly concerned cause I can feel baby moving ALOT and I'm keeping enough down to not go to the ER as of now but i don't know if it's gonna get worse and I feel like I'm not able to function and be there from my family.
