im 17 and iv been on the pill for about 6 months now. i always get my period on the tuesday of the sugar pill. i dont take my pill the same time everyday, and i have forgotten a few times and doubled up the next day. there was one time where i dropped the pill in my car and lost it. me and my boyfriend always use condoms but it broke one day. i used an online ovulation calculator and the day it broke was between the few days it said i was ovulating. its now thursday and i havent gotten my period but i have had a brown spotting and a light bleeding. my breasts usually get really sore a week before my period but they arent sore at all. iv been sleeping alot and getting headaches. please help me! should i take a pregnancy test? or should i wait a few more days...
