Is it bad if i take an ipill contraceptive twice in a week?

Somewhat: You can expect very irregular bleeding if you do this. More concerning is the fact that you would need to use emergency contraception this frequently. It really is intended and approved only for use in emergencies. It sounds like you need to start using a reliable method of contraception and use condoms to decrease the risk of sexually transmitted diseases. Be safe.

Yes - bad: You must take your contraceptive pills strictly as directed.
