Period question

Pardon my ignorance, but when rebecca complained about the cramps and hemorraging in the cafeteria, Im assuming that to mean her period had started, but then she bleeds through her pajamas that night, wouldnt she be wearing a tampon or something?

And then Lucy says she hadnt had her period in months, isnt that like a big deal, they kinda just sweep it under the rug



If it's that bad, you can bleed right through the tampon.
