I had my last period in november 2019. im 30 years old. not sexually active since december. took 8 pregnancy tests to date, and theyve all been negative. i was on depo for 3 months last year but stopped in august. why do i have amenorrhea?

Can check with Dr.: 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. Home pregnancy tests are very accurate by 3 weeks after sex.
