Period was 6 days late this month. so far my flow is lighter than usual and spotty. have never had sexual intercourse. worried. is this normal?

Menstrual changes: It is very common to have occasional menstrual irregularities. If you have been under a lot of stress, if you have suddenly increased your exercise or if you have recently lost a lot of weight, your period may be late or you might miss a period. If your period is unusual next month, you should see a gynecologist to see if there is any specific cause of the changes.
