In October I was 9 days late for my period when I finally started and I'm not sure when I am suppose to have a period this month so far I haven't had one what should I do

I would wait and see what happens and if nothing by the first week of next month than I would make a doctors appt. cause it could be that you are pregnant or that something else is wrong... I am sure its nothing big though! Our bodies play tricks on us all the time but you rather be safe than sorry! Good luck!
