I have started my period for the first time, but its been longer than 7 days. Is this normal?

Answers:

Completely. period are chance surrounded by the origination. Eventually they will second between 3-7 days.

Yes, since your spell is irregular and your body is still getting used to the topical move.
If it last longer than 10 days, consult your doctor, it should second up to 8 days, I don`t know 9 and 10 is pushing it.
But don't verbs too much roughly speaking it.
You may not own it again for a few months until it regulates.
Take concern!

Adolescents?

When I first begin menstruating, mine sometimes last for almost 10 days, that last a year or so, after after a while they started to regulate. After four years, on average, your cycles should start to regulate so you should know what to expect. I woulldn't be too concerned more or less it. If you're worried though, you should patently be in motion to your doctor, since I am most patently NOT one.

Are any of you resembling me?

yeah. my last of 3 weeks!!

Growing into womanhood?

It take a couple of years for your body to adjust, so it is commonplace for irregular period, or long/short ones. Don't verbs.
