When it comes to conceiving, cumulative efficacy is key: the more treatment cycles you try, the higher your chances of success. With this research study, we're trying to better understand the impact of doing 3 full treatment cycles on people's chance of conceiving. Don't worry – we'll ship you a new treatment kit at the beginning of your new menstrual cycle, and only when you tell us to (using the Béa App), so you don't need to store any kits at home.
