I think I got my first period yesterday... I didn't tell my mum cause I wasn't sure... I feel stupid now cause I didn't wear anything last night in case I would tell my mum today and show her but my undies have a few brownish spots with a hint of green... ??? Is that normal? How should I tell her? She's the kind of person who'd get a big toothy smile give me a long talk and keep saying you're growing up and laugh and I'd just start screaming at her!! I've been dreading this for ages! What should I do?
