Welcome to HCM.
Let me first of all wish you both a very happy long married life. It is a good decision on part of both of you to avoid pregnancy for sometime. Better enjoy life and get to know each other better and let the honeymoon cystitis
(Urinary tract infection
usually seen in the newly wed couple) settle down before you consider to have children.
Since you are recently married, intrauterine contraceptive device (Copper T) is not advisable.
May use contracetive pills or condoms
Other options available are Coitus interruptus
(Withdrawal of the penis just before ejaculation
occurs and having intercourse during safe period ( 1st week after menstrual bleeding and 1 week just before expected date of next period).
Have a good time.
