possibly a miscarriage . advice?

Jessica
Came home from the hospital last night and the doctors told me that my levels keep going up and down but only by a little. I had ultrasound done but they couldn't see anything because I am only 5 weeks. I have been a mess and I have no idea how to deal with this :( trying to think positive but it's hard . Tomorrow I'm going back to see if my levels went double but the doctors said that this is most likely a miscarriage:( does anyone have any advice to give me ? This is my first time getting pregnant so i don't how to deal with this.
