That's actually quite normal
if you have a cycle that is upto 30 days at some point you will get two periods in one calendar month.

Your periods are counted from the first day of bleeding until the first day of the next.
1 oct as day one for one period and 26 oct as the start of the next gives you a perfectly normal 26 day cycle.

You don't say how long a normal cycle is for you.

i started my period on feb.1st and it lasted 13 days. then i started again on feb. 27th and it lasted 9 days. i found out april 13th i was pregnant.when did i conceive

i had the same promble in july on the 1st i got my period it lasted until the 5th and than on the 29th i got it until the 2nd of aug. with brown/watery discharge at the end for the 1st-2nd of aug. but i dont know if it was bcause i was treated for a bladdler and kinndy infection durring the month of july. i have never had 2 periods in month. i dont know if im pregnant or what help please!

I had my period in the same month and I had unpoected sex. my 1st period was the October 1st and it ended on the 5th. My 2nd period was October 24th and it ended today and I still feel heavy in my stomach but I am not even flowing but not a lot.

I had my period on October 1st and then another one on October 31st....both lasted 7 days. Does that mean I wont have one for November? But I still got the pain, cramps and stuff a couple days ago but not period....so do I have to wait more?
