Hi ihave started to drink 1 cup of green tea in the morning and i drink 1 cup of slimatee at night and i havent got my period yet. it is late.

Might not be the tea: In a woman with regular periods, some causes of a late period include: excessive weight loss or weight gain, increased exercising, emotional stress, having an illness, traveling, medicines (like birth control pills), hormonal imbalances, etc… Seeing a doctor is a good idea if symptoms are persistent, recurring, or worrisome. Pregnancy is the common cause of a missed period, if sexually active.
