If I'm Not Pregnant, Then Why Hasn't My Period Started?

Monday August 25, 2008
One of the questions I'm asked most often is "Why is my period late?" Although, pregnancy is the most common cause of absence of menstruation (amenorrhea), many times, the women will also assure me that they are definitely not pregnant. So, what else can cause an absence of menstruation?

STRESS, worrying about being pregnant, a new diet, weight changes, being a teenager still having irregular periods, being ill, or having a new birth control or a new medication.

this is the same problem with me but I’m only 13 and I was suposed to get mine yesterday so y is it late? Is it just because I’m a teen cause this should my 4th time getting it and I’m can’t be pregnent because I will never have it till I’m married so why is it a day late?

you are only 13, you’re definitely not pregnant if you’ve never had sex. and you won’t always have it on the same day. you’ll have to wait a while before you can really say which day you’ll start. i’m 17 and i can’t even say which day i’ll start

I’m 15 and have been having my period since i was 11. After a while I worked out the math and figured out that it came every 22 days. This week it didn’t come…It was supposed to be here on wednesday and i finally got it today on sunday. I knew I wasn’t pregnant because I never had sex and won’t till I’m married. I looked it up and it said It could be from Stress(which I’ve had a lot of recently) or increase in exersise (which I’ve also done) so I’m guessing mine was just late from that. If it is only your fourth time Don’t worry about it. When my period first came I had it for six months and then it went away for 3 and then came back again. :)
