I'm 21 and my cycle is about 34 or 35 days. Can I take pills even if they are by cycles of 28? Is there a specific day on which to start every set of pills?

Yes. The pills will readjust your cycle to be 28 days in length, not 34 or 35.

So right after finishing the 28 pills I can take another set immediately?

"You will start each new birth control pill pack on the same day of the week that you initially started it. If you are on the 21-day pill pack, start the new pill pack seven days after you finished the old pill pack. If you are on the 28-day pill pack, begin the new pack after taking the last placebo pill in the old pack.

Start your new pill pack as scheduled above, whether or not you get your period or are still having your period."
