In all cases, we recommend contacting your healthcare provider or Ob/Gyn when trying a new period product if you have a diagnosed reproductive health condition.
Flex medical advisor and Ob/Gyn Dr. Jane van Dis has informed us that, if you have regular uterus didelphys, you should be able to use Flex menstrual discs (including Flex Disc, Flex Plant+ Disc, and Flex Reusable Disc). However, we wouldn't recommend them if you have two vaginas in addition to uterus didelphys.
