I had an period in October which lasted 6 days.. I also had a period in November which only lasted 4 days the first day was a very medium flow that did require a pad,the second day was very light,the third day I was not bleeding and the fourth was pretty much spotting... I have been a little more tired then I usually am and also hugry I've been having off and on hot spells and find myself using the bathroom a lot.. My breast do feel a little fuller then they did before but as for the color I haven't seen any change.. just wanted to know if someone could help?

See what happens when you would expect your period in December. If it doesn't show, or is not the norm, try a pregnancy test.

A shorter period, or one that has less flow, may be due to pregnancy, but periods can just be off from the norm from time to time as well.
