If my due date April 1 2018 how can I determine my date of conception?

Look it up on Google. It will tell you. I looked mine up and it matched what the doc said. Plus your doc can tell you too.

@juliaschade41, oh ok thank you!

@kwaiters1790 welcome! It won't be accurate but it'll be around the time you conceived.
