Embarrassing moments!

So today I was sitting in class and I felt something...I looked d wn and saw that my jean Shorts had a big red stain on them. I wrapped sweater around my waist but because my period was really heavy I thought it in my seep through my light blue sweater also. So at lunch I want to the office and faked sick so I could go home. When I did I looked in the mirror and you couldn't even see the stain. I don't care though, because now I get to chill in bed with my cat have a relaxing day. 
Btw I am a young girl ( not going to say an age) and I have only had my period for about 9 months... Still not used to it. Also I use pads. 
What's your most embarrassing moment? ( it doesn't have to be period related but would be better if I was. )
