Large Cyst, any one experience that while pregnant?

Stephanie • 27 year old, Office manager, Soon to be first time mommy
I have a 9cm cyst that was detected by 7w 5d (I'm currently 14w 5d) pregnant. Some days I'm in so much pain, I'm in the fetal position. 
I'm concerned I can't workout or do anything. Has anyone experienced this?
