The study will take place over 3 menstrual cycles. The first menstrual cycle is considered the “control” phase where you will only use Ibuprofen for pain relief. Menstrual cycles 2 and 3 are randomized. For instance, you could be randomized to use only the UNO + Butterfly pad on cycle 2 and only the DUO set-up on cycle 3 or only the DUO set-up on cycle 2 and only the UNO + Butterfly pad on cycle 3.

For scientific purposes, we have randomized the order of when you will use the UNO + Butterfly pad and when you will use the DUO set-up. For instance, you might be randomized to use only the UNO + Butterfly pad on cycle 2 and only the DUO set-up on cycle 3 or only the DUO set-up on cycle 2 and only the UNO + Butterfly pad on cycle 3. It’s important that you only use the UNO + Butterfly pad or DUO set-up during the specified months.
