No one knows
when.
We know how likely.

Your due date is a guess with a 5% accuracy rate. Ours is a probability distribution calibrated on three million births. Less surprising. More useful.

Three practical picks for the last weeks, with the evidence and its limits. Studies concern the food or technique, not these brands. As an Amazon Associate I earn from qualifying purchases.

Natural Delights Pitted Dates · 12 oz

A smaller, ready-to-eat pack instead of committing to a bulk bag.

Labor research is promising but limited. Date size varies; no ideal dose is established. With diabetes, check your care plan first.

Trideer Pregnancy Ball

Anti-burst ball with pump and guide. Labor-pain evidence is moderate-to-low certainty.

Choose size by seated fit: feet flat, hips above knees. Follow the maker's sizing and inflation instructions; use support for balance.

Lansinoh Massage Oil · 1.7 fl oz

Perineal massage from about 34–36 weeks was linked to fewer episiotomies for first births.

Sweet almond and wheatgerm oils — check for ingredient allergies. The massage technique is what's evidenced, not the brand.
