Hi! I'm having the same issue but I don't know so I'm wondering too.
yes...it does mean your starting your period, no need to worry. just casually bring it up with your mum, i you don't want to speak directally to her why not give her a text or drop a pack of pads into your basket at the subermarket that will give her the heads up. it is your mom at the end of the day she has been through it all too...
good luck:-D.
ps. welcome to womanhood
Oh my goodness, I remember my first period, and having to explain it to Mum. XD God, seven years ago- how time flies.
At first, I thought my brother had put chocolate pudding in my pants as a joke! Then after I sort-of figured it out, I walked around with toilet paper in my underwear for a day. I'm overly shy so it took awhile to work up the guts to tell Mum, but when she was by herself, I kinda just sat down behind her and stuttered my way through "Hey mom, I think I had a period". It's insanely awkward, but it's the one and only time you'd have to say it. EVER! Just laugh your way through it if it makes you feel better. :D
'Gratz, and best of luck!
Omg i have the same problem with her but i've had it for about a year and a half but i haven't gone through any signs of my period. Thank you for telling me what it was :)!!!
