I hadn't thought of this before, and have switched to cloth pads for nighttime. Unfortunately, this means I get a lot of spotting while wearing my cup during the day, necessitating either a cloth liner or black underwear, both of which are in short supply.
Are there others in here who have to consider the effects of EVERYthing on their girly bits due to the looming threat of cervical cancer? It pisses me off...and I can't wait until I've had a few normal paps in a row so I can wear my cup all the time again.
