Thanks so much, Elizabeth!
Not easy to use. Very disappointed. Very frustrating. Wish that I could return it but it is past the window. I didn’t open it right away due to a busy life hahahaa so by the time I realized that this product was a waste for me it was too late. Oh well!

Hi Michelle, If you'd like to email us at [email protected], we'll be happy to get you on track with Daysy so that you may use your device as you originally intended.
I have an infant, and it isn’t possible for me most days to take a basal temp that takes that long to register before getting my son. Also I rarely get three straight hours of sleep. Doesn’t seem like achievable birth control for me right now which is too bad.

Hi Lucille, We know how hard it can be to get 3 hours of sleep with a newborn! Hopefully, you both get to sleeping longer stretches soon, and Daysy can a great help to you at that time. Congrats on the new addition to your family.
So many bugs I’m constantly troubleshooting.

My Daysy is a quick and easy way for me to ensure I have safe sex. I don't know what I would do without it.

Thank you, Lesley!
Daysy has the best customer service! They are always very quick to respond to any issues. I’ve been using Daysy for three years since I got off the pill. My first Daysy got damaged and they sent me another one in the newer version as soon as I sent the old one in. Highly recommend!
