Pink discharge after period has ended and it had lasted 3 days and today it was think and a lot more than the past two days, there is no odor or pain?

No worries: As long as there is no odor, pain or itching you are fine, it is just your period ending. If it lasts more then 7 days go see your obgyn or family doc. Are you taking contraceptives? If there is any chance you could be pregnant do a pregnancy test! if there is a chance for std's get screened! and get your hpv vaccinations if you haven't had them yet! covered by insurance till age 26 (for now) !
