Help... this is new to me, and I'm feeling clueless!

[PatienceLong]

My DD (14) started her periods last June. I expected her to be a bit irregular to begin with, but no - very regular straight away... until now - she has just told me (slightly nervously) that she has now missed 2 periods...? Is this normal? Should we be worried?
I know parents tend to be the last to know these things but to the best of my knowledge she has not got a boyfriend or been sexually active in any way! I will obviously say she is not that sort of girl and has had all relevant 'talks' etc... However, I am very aware that we've all seen stories of parents looking shocked when they discover their child is sexually active... Am I letting my imagination get the better of me? I feel like I'm over-reacting...
I'm hoping one of you lovelies will tell me it's normal at her age/stage to be randomly late etc... if not - what do you advise please?
TIA xx

It could be exam stress.
Why not explain that apart from when you have sex and your expecting, that stress weightloss, changes to eating and may other things can cause this.
Also say that while your on the subject of sex, that you hope she knows about safe sex, that you can get pregnant the first time, and about peer pressure by boys for girls to let them if they love them is wrong.
Yeah that talk.

Good points mummmy2017! Yes - totally agree. She's good at discussing personal matters with me, she told me as soon as she started her periods etc. She has had 'that talk' a few times, but a refresher is a good idea - thank you!
I think because stress/weight loss/gain etc has never once affected my cycle, i'm unfamiliar with how that works. She doesn't seem to have been under any pressure etc... but I'll have a good chat with her tonight xx

Also worth noting that it's still early days cycle-wise, even if she's always been regular so far a random blip here and there isn't unheard of. Make sure she's not pregnant and go from there.

DD had a couple of periods then nothing for 3 months. They do take a while to settle.

I'm so sorry but I would 100% check she isn't pregnant first. A statement of 'she's not that sort of girl' just isn't helpful. I am speaking as a 30 year old woman who had her first child at 15. I was not 'that sort of girl' I was very manipulated by an older boy who of corse I thought to be amazing and before I knew it I was 4 months pregnant totally oblivious as it's such a young naive impressionable age. She probably isn't and it is probably related to other things but just to be sure please check xx
