Pregnancy Due Date Calculator (free) - Sometimes babies measure “off” from where the doctor thinks they should be. Work backwards using your estimated due date to find the day you likely conceived to help clear up any confusion about the baby’s size and state of development.
Let’s be honest, we all know ‘estimated due date’ is never accurate. Yet, we continue to sit here naively thinking that by 40 weeks (hopefully sooner, you know….because it could be as early as 37 weeks!) we will have the baby. Why did I think my son would be early? Now I am shooting myself in the foot for not remembering that it could also be up to 42 weeks.
