Can I use and benefit from Tempdrop if I am postpartum and getting up frequently during the night?

By Tempdrop team

During postpartum, you will have to pay attention to your body’s signs to understand whether or not you’ve started ovulating again. If you start bleeding after 56 days, it is most likely your period. Checking your cervical fluids is another way to understand if you’re already fertile. Taking your BBT is considered the best indicator for understanding if you have ovulated, but we recommend using all three signs!

Many women find it hard to take their morning waking temperature while they’re nursing and need to wake up every few hours during the night. Tempdrop is designed specifically for that. Since you will be wearing it throughout the night, it will learn your typical sleep temperature pattern and detect your true nightly sleeping temperature no matter how many times you wake.
