I was visiting my boyfriends family during winter break and realized I had forgotten my birth control. Luckily I had my next months' pack on me that hadn't been opened. I started on what I thought was supposed to be the dark blue pills (.250 mg norgestimate) and didn't realize until now that I was supposed to have started the light blue pills (.215 mg norgestimate). Should I finish the dark blue pills that I have mistakenly started and then start the light blue after? Will this delay my period since it will think that I will be taking the green pills next? Does this affect it's effectiveness since I'd be moving down in mg of norgestimate if i move from dark to light blue pills?
