Teenage periods

[Pinkkittens292]

Just wondering if any mums have adolescent daughters who experience irregular or missed periods?

My daughter has just turned 15, started her periods 7 months ago in April this year.
She's healthy, and a healthy weight. Has recently had a growth spurt.
Her periods began fairly regular, but then in August she had a particularly heavy one (only 22 days after previous one).
She then went 34 days and had a more "normal" one.
It's now been 40 days and she's had nothing since the end of September.
She's not sexually active and tells me everything.
However she has been very stressed over school (friendship) issues this month and is now worried about her irregular cycle.
I keep reassuring her, but how long do I wait before making a GP appointment?
It will be a female doctor that we see but no idea what the GP will do?

Following as my DD hasn't had one since the start of September and I don't know if it's a job for the GP yet or not. I'm just stuck knowing what to do, though I did tell her she's probably need a PT to test her reaction and she wasn't bothered.

Irregular periods are totally normal at the start, up until the first two years. I wouldn't waste GP's time for now. www.nhs.uk/conditions/irregular-periods/
Best to keep a diary of when, but I wouldn't say it's anything to worry about.

I didn't start my periods until fifteen and they were pretty erratic, it turned out I have PCOS , but lots of my friends had similarly off cycles and it just took a couple of years to settle down into a pattern and they have no ongoing issues. Hers don't seem that off (I'd go three months with nothing then bleed for five weeks at a time then have two weeks break then get another period). Stress can definitely have an impact but I wouldn't be worrying too much at this stage, it's early days

I believe it is entirely normal for periods to be irregular to begin with, I think it can take up to 3 years to regulate?

Irregular periods are totally normal for teenagers. They're annoying but nothing to worry about unless there are other symptoms to suggest other problems.

There are apps such as Clue to track periods. It'll give her an idea when a pattern does start to form

Agree with Spaghetti - it's normal for them to take a while to settle. Think there may even be something on NHS choices about it? I looked recently as poor old DD started hers at just turned 10, which is rubbish TBH.

Mine were irregular for around 2 years, sometimes it would be 7/8 weeks in between but they eventually became regular. Advise her always to carry pads/tampons just incase

My dd started in year 6 too.She now has an app to track them so is totally used to them being a bit off sometimes.All normal.

I would say that's normal given she hasn't been started that long ago. They take awhile to settle. I was almost fifteen when I started mine ( now 46) and I remember going into the 40 + days bracket then sometimes I'd go 20 days so could never predict. My daughter started hers at 11 and were every two weeks at first, now they're a little more settled after a year and a half but still not dead set to the day, some months are 21 days ,or anything up to 30! I've never been really regular either.

I dont have a daughter but I remember mine, they were all over the place for a couple of years, then clockwork for the next 30 odd yeRs before going all over the place again.
