Is there any love between you and your husband? If yes then while you need physical help to help you recover from this operation he probably needs psychological therapy to deal with the way he is acting. His refusal to buy you the medicine might be a sign of denial since you are both young but you probably will not be able to have a child and he is finding it difficult to deal with it. At this time you need a lot of rest and sympathy and loving and I truly regret you are not getting it.
