I had sex last month got my normal cycle. This month no sex at all and three days late. What could this be???
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.
