Prementral symptoms: There is a normal change in your hormones throughout your cycle. Some women feel more emotional before the period. Some get headaches. There are several options for treating these symptoms. See your doctor for a check up and treatment.

Likely u get too: Emotional from a surge in Progesterone which is the hormone that gets elevated after ovulation until the next menses. I won't worry much about it. Watch comedy shows to offset the bouts of sadness.
