I had unprotected sex , I took plan b.. I got my period it extended for about 9 days.. I had protected sex after I got my period.. almost a month and a week passed and I still don't have my period should I be worried?

Probably not, but it wouldn't hurt to try a pregnancy test. Anytime you have sex, protected or not, pregnancy can be possible.

It is not uncommon for cycles to be off a bit after using Plan b, so that may be the cause.

If you try a pregnancy test, and it is negative, wait and see what happens when you would expect your next period.

Thank you.. but the thing is that I had sex twice.. and I checked the condom for any holes or rips but it seemed fine.. is there any possibility at all because I'm getting really paranoid

Yes, there is always a possibility of pregnancy when you have sex. Try a pregnancy test. If negative, wait until you would expect the next period and see if it shows. Again, it may be your cycle is off from the plan b and you just skipped a month.
