Natural Cycles Code Checks, Day by Day
Every Natural Cycles code check from the last 14 days, plotted by the day it ran. Green is how many came back working. Red is how many naturalcycles.com would not accept. That is the checkout testing you did not have to sit through yourself.

What These Numbers Mean
A code check is one result for one code. Most are our agents applying it to a real cart and reading the order total before and after; the rest come from tracked orders and from shoppers reporting back, as broken down above. Worked means the code was accepted and the total went down. Would not apply means naturalcycles.com refused it on that cart. That is not the same as the code being fake. The usual reasons are:
- It expired or the store switched it off after it was published.
- It was single-use and had already been redeemed.
- It only covers certain categories, brands or individual products.
- The cart did not reach a minimum spend.
- It is limited to new customers, a first order, or an email sign-up.
- It cannot be combined with an active sale or another code.
- It is tied to a different country, currency or membership.
So a code that failed one check can still work on your cart, and the success rate (checks that worked divided by all checks) is best read as how easily Natural Cycles discounts apply in general, not as a verdict on any single code. Hover any bar in the chart to see that day on its own.
When Natural Cycles Runs Sales
Recurring events worth timing an order around. Windows shift year to year, so treat them as a shopping calendar rather than a fixed date.
- late NovemberBlack Friday Sale
Offers steep price cuts of up to 50% off annual subscriptions alongside complementary basal thermometers during the holiday weekend.
- first two weeks of JanuaryNew Year Resolution Event
Features promotional discounts on yearly plans aimed at users prioritizing health tracking and hormone-free wellness goals for the new year.
- early MarchInternational Women's Day Promo
Runs special promotional pricing and bundled device discounts on annual memberships in celebration of women's health awareness.
When Do New Natural Cycles Deals Drop?
Our agents log every new Natural Cycles promo code and deal the day it goes live, and record what the working ones took off a real cart. Here's how many landed each month over the past year, how deep the discounts ran, and when it pays to wait.

Before You Buy at Natural Cycles
What shoppers ask most about Natural Cycles.
›Can promotional codes be combined with other offers or sale prices?
Promotional codes cannot be stacked with other active discounts or applied retroactively to existing subscriptions. Each promo code is limited to a single use per customer account.
›Are there any subscription plans or merchandise excluded from promo codes?
Promo codes apply exclusively to annual subscription plans and never discount monthly rolling memberships or hardware bundles like third-party wearables.
›How do I turn off automatic renewal for my subscription?
You can disable auto-renewal by logging into your account, navigating to Billing under Manage Account, and selecting cancel current subscription at least 24 hours prior to your renewal date.
›Can I use Natural Cycles if I purchase my subscription in a different country?
Your subscription works globally across supported regions, but medical device regulatory clearances require that your app settings match your current country of residence.
How We Verify Natural Cycles Codes
Nothing goes up here on trust. A Natural Cycles code is collected, applied to a real naturalcycles.com cart, dated the last time it took money off an order, scored on what came back, and pulled once it stops clearing. Promotions have no code to run through a checkout, so those are dated when they go live and dropped when they lapse. Here is how far that has got on this page, and every change the agents logged along the way.
