Fertility Signs
Most menstrual cycles have several days at the beginning that are infertile (pre-ovulatory infertility), a period of fertility, and then several days just before the next menstruation that are infertile (post-ovulatory infertility). The first day of red bleeding is considered day one of the menstrual cycle. Different systems of fertility awareness calculate the fertile period in slightly different ways, using primary fertility signs, cycle history, or both.

Famous quotes containing the words fertility and/or signs:
“I will go root away
The noisome weeds which without profit suck
The soils fertility from wholesome flowers.”
—William Shakespeare (15641616)
“Among all the modernized aspects of the most luxurious of industries, the model, a vestige of voluptuous barbarianism, is like some plunder-laden prey. She is the object of unbridled regard, a living bait, the passive realization of an ideal.... No other female occupation contains such potent impulses to moral disintegration as this one, applying as it does the outward signs of riches to a poor and beautiful girl.”
—Colette [Sidonie Gabrielle Colette] (18731954)
