Stopping contracepton without husbands knowledge

slmz mufti.im 20 years old,husband is 22.we are married for a year and a half,i would like to have kids but he insists not now for financial reasons,yet he has money for fishing and hobbies.he has also refused to move out up until recently as i have had to insist. is his reason for making me take contraception valid?should i continue to use it under his command or stop without telling him? i am afraid if i get pregnant he will be unhappy and i fear the feeling that will bring as my getting married was not something his parents wanted so early
