Luteal Phase · Day 22
You're in your luteal phase — energy may dip mid-week. I've adjusted your workout plan toward more restorative movement and added magnesium-rich foods to today's nutrition guide.
Should I skip my strength session today?
Not necessarily. Your sleep score was 78 last night and your mood log was neutral — that's manageable. I'd suggest the 30-min low-intensity option rather than skipping entirely.

Why starting HRT at 52 vs. 62 changes your heart disease risk

Hormone therapy's effect on your heart depends on when you start it relative to menopause. Starting within 10 years — or before 60 — can reduce heart disease risk.

Pregnancy
Why you wake at 3am in early pregnancy

That classic 3am waking starts early — rising progesterone changes sleep architecture, not just bathroom trips.

Trying to conceive
What BBT can’t tell you about fertility

Basal body temperature confirms ovulation after the fact. It can’t assess egg quality, tubes, sperm, or progesterone.

Why the same meal hits differently across your cycle

Insulin sensitivity can drop about 50% from the follicular to luteal phase. Same plate, different blood sugar.
