Gallbladder issues..

Brianna
So I've been in and out of the ER, and in and out of my OB office for the last couple of weeks. It started with My upper abdomen under my boobs hurting super bad, and has turned into not only the pain, but not being able to keep food down, headaches, and my legs swelling. Has anyone experienced this? My OB said he's going to "check my gallbladder" and I see him tomorrow. I get progressively worse every day. And I'm worried about the HELLP syndrome. 33 weeks & 3 days pregnant.
