I need help GIRLS ONLY

Put some tissues to stop the flow. Tell your mom আপনি got it. She has to have pads right? Ask her to buy আপনি some.

She should understand. Periods are perfectly normal. আপনি just need to relax a little and wait until she gets home, then আপনি can just come out and say that আপনি had your period and then আপনি and your mom can go out and get whatever আপনি need from a store.

Use toilet paper দ্বারা rolling enough where it's thick enough so there's no leakage, for now till she comes home, আপনি can tell her, she'll help আপনি go to the store and pick up some pads (or tampons if আপনি have no fear to use them) take some aspirin if আপনি have any cramps.

Well, just tell her. Trust me, she'll be happy (or so I hope). Moms always get happy when this happens. When I got my period, I just sat at the toilet and ব্যক্ত "MOOOOOM!!! THIS IS URGENT!!!" (she just came and when she saw it she hugged me and told me to take a bath) If not just text her "...i got my period." and wait.

I came here just to say that I am a guy

And there's no reason আপনি can't just tell her
Its a natural body function, nothing to be ashamed of

Firstly, calm down. It's okay, it's going to be fine.
Secondly, do আপনি have any sanitary towels in your house? (I wouldn't recommend tampons if this is your first period). Maybe in the bathroom অথবা in your mum's room? Get one of them and use it. If not, get some tissue/toilet paper into a wad and use that (several sheets should be used). If আপনি are in any pain আপনি should take some paracetamol (I don't know what dosage, but it should say how much আপনি should take depending on your age on the back.)
Next, call অথবা text your mum. Maybe wait until she's definitely out of the doctor's room. She'll be able to pick up some sanitary stuff at a ভান্দার somewhere and she'll be able to give আপনি whatever support আপনি need (it can be scary for the first couple of times, but don't worry). Just tell her straight what has happened.
If আপনি need any আরো help, just ask :) I hope it turns out okay.

Well first off tell your mom. If আপনি dont tell her then she wont know. If আপনি can find anything to stop the bleeding then use that. Text ur mom and tell her. Its natural evey girl gets, Believe me I freaked out the first time to, and I wasnt even at my house, I was in orlando with my aunt. So just take a deep breath in and আপনি will be good. Also another tip, when ever আপনি did start make sure আপনি mark it down somewere so আপনি will know পরবর্তি time when আপনি are suppost to start. I believe i covered everything! Oh and u might get cramps and ur lower back will start to hurt when আপনি know your close to starting your period. And আপনি will be kind of bitchy the week before আপনি start. And remember চকোলেট is your very best friend when আপনি are on your period. Also if আপনি have really bad cramps and your back is driving আপনি crazy take some menstrual relief, আপনি can get it at walgreens. It really helps! Oh and আপনি can have your period up to 3days, 5days, 7days, অথবা even longer. But usually I only last till 7days, luck if its 5days, but just a heads up!!! Hopefully this helps!!!

Tell her:
"Hey... Mom? ...I think I'm dying..."

That worked for me! :D

When I got mine, I like FINALLY!! Then the cramps and all that good stuff followed. I just crawled into বিছানা with a block of চকোলেট a notebook and sketchpad, drugged myself with one too many painkillers and spent a week staring at all the lines on my hands. XD

My mom thought it was hilarious.

নমস্কার tell your mum she can help you. When I got my first period I was on holiday with my Dad and had to talk to যেভাবে খুশী lady. Your Mum will help and its better than telling a complete stranger and being with your Dad who didn't know what to do

Dont worry. It's a natrual thing so just tell youre mom.
secondaly put some tissues and wait for her to come

দ্বারা the way... I dont think u should be asking প্রশ্ন like this here. Becz if u say GIRLS ONLY maybe boys are gonna get আরো curious. It's not like they wont even read the প্রশ্ন if আপনি tell them not to...
Im just saying :P
