What causes your menstrual cycle to be late?

Answer 1

Lots of things can cause your period to be late. Stress is one of them. Having irregular sleep patterns does cause a stress to your body, even if you don't feel stressed out. Try to regulate your sleep, but also look for other factors that may be the cause too.

Answer 2

Absolutely. Sleeping pills slow down a person's metabolism. I took sleeping pills for a month one time and I didn't have my period the next month. Sleeping pills can mess up the thyroid as well. Sleeping pills will also cause weight gain. I hope I helped you some. I am studying to be a nurse.

Answer 3

Firstly, remember that menstrual cycles are never all the same length and up to a weeks variation from your average cycle is normal. If you're in your teens or going into menopause some irregularity in your cycles is completely normal too. Otherwise things that could delay menstruation include stress, ill health, radical lifestyle changes, or radical weight changes. Pregnancy too, of course.

Answer 4

Yes, a change in sleeping patterns can cause a persons period to be missed or delayed.
