What is your most embarring moment ever! Make me feel better!?

Okay so this kind of a girl thing so guys, dont get disgusted. Me and this guy I've liked for really long time were sledding with my niece and nephew. I had these white pants on with a black jacket and matching boots. I slipped on one of the sleds and skidded down the whole slope on my . It isn't over yet. I expected to hear my crush laughing but instead he got really red and excused himself saying he needed to pick his mother up from his sisters house, and his mother was home! (I knew this for a fact) I wondered what was wrong and I saw my 3 and 4 year old niece and nephew crying. I asked them what was wrong and they said I got hurt and was bleeding. Turns out, I had my period and I was leaking through my white pants onto the snow. My left a whole trail down the slope to where I had fallen. We never went sledding or in the snow again.
