MrsComp... actually provera doesn't give you a real period either... It builds up your uterine lining and forces a bleed, but it doesn't cause ovulation, and not a real period.
Temps taper off different per person, as we each have different body chemistry, and there can be environmental factors that change things too... but from most charts I have seen, temp sort of start dropping right before AF shows up, and is typically low the day it starts, but I have seen the opposite of that too... after charting a few cycles you will find what your pattern will be.
I think staying positive and keeping the appointment and starting Maca are all good things! Especially as you have not had any regular periods off of BCP yet it seems... remember it can take 6 months to a year for your system to truly regulate after BCP, sometimes even up to a year and a half. After I found this information out I swore I'd never go back on synthetic BC again. : The things docs SHOULD tell you but don't to help line their pockets from endorsements from drug companies... /rant
You know my thoughts on Maca. That's my highest recomendation.
My temps are still up but I am expecting them to drop tomorrow. Still cramping in my lower back like AF cramps.
