Always Ultra Thin Pads with Flexi-Wings, Regular, Size 1 36 Each - (Pack of 2)

These are very discrete and absorb so much. I have a heavy cycle and never worry with these. They stick/hold well and don't come undone from the underwear. No skin issues although I have had them stock to my inner thigh due to user error but no allergies or anything left behind on skin.

I've been using this product for 15 years. They're durable, comfortable, have good absorbency, and are discreet. I haven't been able to use other brands since because I'm allergic to them. If you've never used them before, I recommend buying them so you can be more comfortable during your period.
