Good morning guys. I take Lo Loestrin FE. Sorry if I missed spelled. I take it everyday at the same time right before bed however when It was time to take my first brown pill I couldn't find my pack, so in a worry I just started a new pack. I was suppose to get my period on Tuesday however never got it.. I'm kind of concerned because I am sexually active and just wanted to know if this was normal. Please comment when have the chance. Thanks in advance.
