Pregnancy brings significant physiological changes—elevated heart rate, reduced HRV, sleep disruption, and more. Without adjustment, these normal changes would incorrectly impact your biological age score. My Bio Age now includes specialized Pregnancy Mode that intelligently adjusts how metrics contribute to your Index.

How Pregnancy Mode works

When enabled in Settings → Medical Conditions, the app adjusts the emphasis of each metric based on whether it's meaningfully affected by pregnancy:

Reduced Emphasis (normal pregnancy changes won't hurt your score)

Resting Heart Rate — elevated RHR is expected during pregnancy
Heart Rate Variability — reduced variability is normal
VO₂max — relative capacity decreases with body changes
Sleep Duration — disruption is common
Respiratory Rate — slight increases expected
Wrist Temperature — elevated temps normal
Blood Pressure — highly variable during pregnancy

Emphasized Metrics (still meaningful during pregnancy)

Recovery Capacity — recovery patterns remain informative
Active Energy — activity is still valuable
Walking Heart Rate — relative measure stays valid
Sleep Regularity — consistency still matters
Oxygen Saturation — stable metric

Visual indicators

When Pregnancy Mode is active, you'll see a "Pregnancy-Adjusted" badge on your MyBioAge Index. Settings shows which metrics are adjusted, and the mode can be combined with pacemaker mode if needed.

Enabling Pregnancy Mode

Navigate to Settings → Medical Conditions and toggle Pregnancy Mode. The app will immediately recalculate your Index using the adjusted weighting. Disable it anytime after your pregnancy to return to standard scoring.

Pregnancy Mode is available now in My Bio Age version 1.0.14 and later. Track your biological age throughout pregnancy with confidence that the algorithm understands your unique physiology.
