Help on best adhesive pad products please?

May • Very Happily Married. Wishing for that little one to complete us
This may only annoy me, but here goes. I'm tired of using pads during AF that do not adhere properly to my underwear! They do at first, but after going to the bathroom a couple of times they tend to fall off. Last week one came loose and ended up travelling down my jeans leg ending up as a lump by my shin!!! It was funny, but thank goodness I was at home. Do any of you ladies have a (sanitary napkin) product you favour in terms of its quality adhesiveness? I'd really appreciate some suggestions. Thank you!
