Can you have contact with ur child after adoption

So basically last week I gave birth to a little girl and were thinking of putting her up for adoption cause we're having financial difficulties and we know that we won't be able to give her life that she deserves. It's the hardest decision that I've ever made but I know it's for the best. 
So anyway will I as the mother be able to have contact with her in the future? 
Please please if you know can you tell me I need your help
