Confused about conception?

Baleigh

🤔 SO my husband and I didn't start trying to have our second baby until June 1st..that is the very earliest that his little spermies started to enter my body 🙊 my last period was May 15 but since I know exactly when we started trying I put it my "date of conception" as the 1st of June. It's saying I'm 7 weeks 2 days but isn't that's impossible considering We didn't start trying until June 1st?? Am I missing something with conception LOL I know this sounds like a dumb question but I need answers. I don't go to dr until this Wednesday
