Most doctors/midwives will count 40 weeks from the first day of your last menstrual cycle. They do this because the moment of ovulation can be different with each woman, making it difficult to predict exactly when a baby was conceived. If you do know whn your ovulation, and therefor the conception, took place, the baby will be born 36-38 weeks later.
