I haven’t actually used these on my period yet, but I know they will be perfect. I even ordered more. I had a problem with the pad part of period undies not extending enough in the FRONT. The undies would shift back as I wore them and I would bleed off the pad in the front. Well, the pad goes alllll the way up on these in back AND front, which is exactly what I wanted. They are quite padded and at first touch feel like they won’t be wearable outside the home, but then I tried them on under a pair of looser pants and I couldn’t see anything! I specifically did get the biggest, most padded ones because I am a SAHM and I literally don’t have to leave my house when I’m on my period so I didn’t care how obnoxiously diaper like they may be, but I was pleasantly surprised that they aren’t diaper like at all. I highly recommend! I ordered my usual size L, and they did shrink a tiny bit in the wash but still feel comfy. If you’re in between sizes, maybe size up so seams aren’t digging in.
