Pregnancy

Pregnancy gets its own kit because the tools needed change so much across the three trimesters and into labor: due-date math at the start, IOM weight-gain tracking through the middle, daily kick counts in the third trimester, contraction timer when it's time. Plus the general-baseline tools (BMI for pre-pregnancy, sleep cycle for the bad nights) and the documentation tools (PDF assembly for hospital paperwork). Everything stays on this device — no upload, no account.
