My period cycle for the current month (October) was due on 2nd or 3rd, but I haven't got them as yet. I am concerned, because we have a family event on 7th November, 2021 which I need to attend. It will be a difficult situation for me if I do not get my periods as per schedule this month. Hence, I wanted to reach out to get some medical advice to possibly delay the next cycle to come after 7th November. All my periods in previous months have come as scheduled with no issues. Please advise, thank you.
