Lmp and scan different in a weird way

I always heard about lmp and scan time, age difference. But i never heard the opposite. If count from my lmp. Im 4 weeks 3 days today. But scan.. im 5 weeks. Why so weird.

Both are usually just a rough gauge. LMP based on what the scan shows, and the EDD is based on your baby’s size during the scan. I never really bothered about the weeks till later in the pregnancy when my baby’s weight gain became slow. At 36 weeks her scan shows 33 weeks instead hence my EDD is pushed further. Just follow the first scan 😃

oic thanks for sharing!

because it’s hard to determine the exact ovulation and fertilisation date. usually based on best estimation by gynae. it’s just few days difference, any reason you are worried?..
