How we make money
Fertility Days is free to read. We may earn commission from some links, and it never changes what we write.
Updated Oct 18, 2026
The short version
Some links on Fertility Days are affiliate links. If you click one and buy something, the seller may pay us a commission. You pay the same price. This is how we keep the site free and independent of advertising.
What commission does not do
- It never changes what we write. If we recommend or link to a product, that is because of the evidence, not the commission.
- It never decides which products we cover. We cover products that pay us nothing when they deserve it.
- Brands cannot buy placement or "sponsored" coverage.
What commission can do
When the same product is sold in more than one place at the same price, we may link to the seller that pays us. If one option is cheaper for you, we link that one.
How to spot an affiliate link
Links to sellers go through a fertilitydays.com/go/ address and are marked as sponsored for search engines. Buttons that say "Visit" lead to the seller's site.
Networks and programs
We may join affiliate programs run directly by brands or through networks such as Impact, Katalys and the Amazon Associates program. As an Amazon Associate, we may earn from qualifying purchases. Whether a given brand pays us does not change what we say about it.
