I want to have twins in my first pregnancy so what should i do? should i follow some health rules or sex rules or should take treatment from doctor?

Double the pleasure: Well, Congratulations on "doubling your pleasure" with a twin pregnancy. Multiple gestations are also more complicated for OB MD's to provide care and treatment due to a number of possible complications. Find a good OB MD who may also consult with a Maternal Fetal Medicine specialist and please follow their advice to the letter for a safe outcome.
