Anyone on here ever deal with a liver cyst?

Long story short since I had my daughter 4 months ago I have been having awful pain every now and then. All signs lead to gallstones. On Monday I had an ultrasound and the tech told me I have gallstones and to make a doctors appointment in a weeks time. Well on Tuesday they phoned and said I am scheduled in for an mri as they think I have a large cyst on my liver around 5cm. They said they aren’t concerned as they think it’s just a cyst but it needs to be confirmed 😓😓 any help or advice is appreciated. As if having an ill baby on home oxygen isn’t enough
