Ever since I had my son (almost 10 years ago) my period has been consistent, anywhere from the 1st to the 5th of every month. The past 3 months, however, it seems to be going out 5 days like the 10th, then the 15th, etc. I have been under a bit of stress, but stress isn't really anything new to me and the fact it has been doing this for the past 3 months just had me a little worried. Just kind of wondering if this is something I should be worried about or if this could be completely normal? Thank you for any advice!

That's usual in women as they get older. Plus stress can cause you to miss your cycle or it to be late. Worry if your flow is to heavy or your cycle last for more than 8days
