On ovulation day i spotted little red blood then for 2 days i had little brown discharge now i am 1 day late for my period?

Possible reasons...: In a woman with regular periods, causes of a late period include: excessive weight loss or gain, increased exercising, emotional stress, having an illness, traveling, medicines (like birth control pills), hormonal imbalances, etc. Seeing a doctor by video or in-person is a good idea if symptoms are persistent, recurring, or worrisome. Pregnancy is a common cause (home urine tests are accurate).
