Flex disc or similar?

This is so embarrassing to ask but has anyone here who is in a larger body used the flex disc? I’m just curious/concerned if it may be hard to use because of having a big belly/not super long arms… but I just got my period back after hormonal bc for years and I’d rather try one of those than tampons for a whole plethora of reasons, but thought I’d see if any of you lovely people with periods could help a sister out!
