So Ive heard about some drugs that help delay the menstrual cycle. Can u tell me the names of some n how they work. i would also like to know the side effects if any.

How do you mean 'delay'?  as in each monthly cycle delayed by a week or two? (there are contraceptive pills that can do that - see a doctor) or delay them starting altogether?
