Well I finally got my period, I guess it's going to come on the second day of my placebo pills!Phew :d , well there should be 4 different kinds of colors on your orthro-lo first the white pills (the active pills) , then the light blue (ovulating ) then dark blue(dropping, getting close for period)then green pills(sugar pills, don't have any affect),well bellaxox, it could be stress or your body is still adjusting to the pill just give it time, if you have had unprotected sex you could be pregnant, but not neccessarily, if u think u are test for it, and if not just wait a few days, you'll be fine!!

:d hope this helps!!!
