Affiliate Disclosure
Last updated: May 3, 2026
The short version
BumpMath is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. As an Amazon Associate, BumpMath earns from qualifying purchases.
When you click an Amazon product link on this site and make a purchase, Amazon may pay BumpMath a small commission at no additional cost to you. That commission helps cover the cost of running this site so the calculators, articles, and clinical references stay free.
Who runs BumpMath
BumpMath is owned and operated by Samantha L. Fox, RN, BSN, MSN — an Emergency Department nurse with over a decade of bedside experience and a current officer in the United States Navy Nurse Corps. The medical content on this site is written, reviewed, and signed off by her.
How we choose products
Product recommendations on BumpMath are based on what we'd genuinely suggest to a friend, family member, or patient. We do not let affiliate commissions influence which products are recommended. Specifically:
- Clinical guidance never changes for a commission.If a product isn't evidence-supported, we don't recommend it — regardless of whether it carries an affiliate link.
- We disclose every affiliate link.Every product card on this site is marked with a "Sponsored" tag, and outbound product links carry the standard
rel="sponsored noopener nofollow"attributes per Google and FTC guidance. - We don't accept paid product placements or sponsored content disguised as editorial.If we recommend a product, it's because we think it's a reasonable choice — not because someone paid for placement.
FTC compliance
This disclosure is provided in accordance with the Federal Trade Commission's 16 CFR Part 255: "Guides Concerning the Use of Endorsements and Testimonials in Advertising." If you have questions about how we handle affiliate relationships, please email hello@bumpmath.com.

Editorial independence
BumpMath is a clinically-reviewed pregnancy and fertility resource. The presence of affiliate links does not influence our editorial coverage. Calculators are built from peer-reviewed research and professional society guidelines (ACOG, ASRM, AAP), and articles cite the primary literature behind every clinical claim. Affiliate revenue funds the site; it does not shape its content.
