Help, I am freaking out. First day of period, usually it's quite light but I used a night pad as all I had, thought all was fine, I was super busy in work, at my desk all morning and now I pop home for lunch to find blood has leaked right through my trousers, pad is totally soaked. I'm freaking out that the light grey chair I sit on in the office has blood stains on it now. I work with nearly all men so it's obviously me. What can I do?? Or say if there's blood stains on the chair... Has this happened to anyone before? I'm so embarrassed.
