Flo’s Symptom Checker

What could your symptoms mean?

One in 10 of us¹ has a female health condition like polycystic ovary syndrome (PCOS) or endometriosis. But getting a diagnosis can take up to 12 years².

Flo wants to change that. We'll give you the information you need to have a confident conversation with your doctor about what’s going on inside your body.

“Very helpful in managing my PCOS and helping me see patterns of things that were concerning. I was able to give my obstetrician and gynecologist a very detailed chart that on my own I would not have been able to.”

Frequently asked questions

Yes, you can track your symptoms throughout your cycle in both the free and Premium versions of Flo.

We have also launched a Symptom Checker tool for Premium members.

This works by asking you a series of questions about your symptoms to see if they match common signs of female health conditions like endometriosis and PCOS.

You can then take this information to your doctor for personalized medical advice, support, and a referral to a specialist for further tests if they think this is necessary.
