i am doing something called lunaception. You sleep in complete darkness your whole cycle except for days 11,12,13 on those days you turn on a nite light. I have done that for awhile and it works with making your cycle 28 days, well I was looking at the calendar and I get af the week of my wedding not cool. So, I decided to change my cycle a little, I am trying to match my cycle to the moon's, there is a full moon that started yesterday and lasts three days. So, last nite I turned on the nite lite and will leave it on for two more days, I am hoping by may (that is when my weddingmoon is) it will be adjusted by then. I was also going to say this lunacaeption helps with getting pregnant or not, if you don't want to get pregant don't have sex the days with the nite lite on. If you do wanna get pregant have sex the days the light is on.
