Is she weird........?[ Mothers answer please]?

Well my period usually comes twice a month and sometimes it's on for about 10 days. Well it just over today and lasted about 6 days and my mother asked me earlier today if it still was on and i said yes it will be until the next 10 days! Because i had no clue it was over until i changed....... I threw the pad in the garbage and couple minutes later she is throwing a fit saying how i lied about my period being on and how i'm pregnant and blah blah blah! Wow she's stupid she actually looked at my pad that i threw in the garbage and showed it to me!!! I'm 17. Why is she acting like a dum A**? Would you do this to your daughter if so why?
