Marriage advice

My husband and I have been married going on 2 years. We have a child together which is what pushed us to get married to begin with. I am so unhappy. There is no particular reason why, I’m just unhappy with our marriage. I don’t know what to do or how to even go about fixing it. All i want to do is leave. Is there any advice from anyone who has been through this feeling? If so, please help.
