🔎 Personal & Cycle Details

(Optional) Biological and lifestyle factors like family history, age & fertility treatments can affect twin likelihood.

How this works (simple)

  1. Ovulation day = LMP + (cycle length − 14).
  2. Fertile window = 5 days before ovulation up to ovulation day.
  3. Boy recommendation (Shettles theory): intercourse on ovulation day or 1 day before may favor male sperm.
  4. Twins hint uses age & family history for a basic heuristic.
