    Super plus leakproof

    I’m a heavy bleeder so wanted to try these. Unfortunately in an afternoon I bled through. Still not enough for my heavy glow

    I Was Hopeful

    Firstly, I was so excited to receive these since it looked like it was going to help me on my heavy days. However, there was some leakage from the sides on my first day, which stained my pants. Very unfortunate. On the other days, they worked well.

    Secondly, I’m usually a medium in pants and undies, and that’s what I ordered, but these are a bit too tight. If I order next time, I would order a large.
