Absolutely Your period is a definite indicator. Most women are fertile even before their period returns but you almost certainly are if you've had a period The act of breastfeeding is not a contraceptive. The hormones released when breastfeeding help to slow the return of your fertility and therefore your period.It all depends on how old your baby is and how much it sucks, the more the baby sucks the more the hormones are released.
So the less you breastfeed (as baby gets older, when you go to work or when baby starts solids) the less those hormones limit your fertility.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
