period underwear/diapers became a lifesaver for me before i went on BC. i used to have severely heavy flow so i was bleeding through overnight pads (even put a towel under me when i slept 😭) and sleeping w tampons in is dangerous so i bought some and i felt so much relief. i wasn't ruining my sheets or pj pants anymore so i slept so much better. only thing i hated was they took up the entire trash can in my bathroom LMAOO
