Hi there, I am 30 years old. I had my son at 15 years old & always had my period on time. after the birth of my son I became irregular. Ever since then my period has always been irregular I would like to know exactly when is it that a woman ovulates during her period Or after and how long of a window do we have? I know every woman is difference, but I just want to have an idea thank you for this matter god bless!!!
