There are many factors. Stress and amount of exercise/activity can affect the timing. I would say stress is probably the factor. If you are a week late, you may want to take a pregnancy test. Many things can cause this. It could be stress, pregnancy(dont automatically think that) Change in diet or excercise..an etc...Give it a couple of days before you begin to worry If you have never had a child before, I don't think that it is a big issue. Women tend to have irregular periods until they have their first child. I have never had regular periods, but I have checked out to be healthy and normal. I have actually gone 2 months without a period, but according to those I asked, there was nothing wrong. If you have had a child before, it is normal for your period to change a little if your lifestyle has changed.
pregnancy
What if you are three days late for your period? It's normal for there to be around 7 days variation from your average menstrual cycle. A few days 'late' isn't a big deal, as long as you're not sexually active no reason for you to worry about it.
stress?
You are not possibly pregnant until it is a month late. Don't stress it. Cycles can vary from 28-38 days normally.
Haven't Started
Probably not pregnant. You just had a short period, for whatever reason.
about three days into your 'white' section of your pills is still normal
no, only if it is a week late and you have had it for more than three yrs
It means your period is five days late. Only you know your chances of being pregnant.
