The things not to do when you use DuoFertility:
Run out of adhesives – ask the team and they ship this to you super quick – so stay on top of your “stock”.
Leave the cat playing with the sensor – Titi likes to play with the sensor, and she made it disappear for a few days during my luteal phase. I only found it when I hoovered behind the sofa.
Due to those 2 mistakes – I have no idea if I have ovulated or not.
