How many weeks am I?

Gialu • Wife 💍 mom💙💕

I realize this is a dumb questions but I use 3 different <a href="https://play.google.com/store/apps/details?id=com.glow.android.baby">baby apps</a> ( probably my first mistake) but all have different due dates! My last period was May 2, and I conceived on May 17 based off of ovulation test and the only day we had sex. It’s only down to the days but I’m either 5 weeks 4 weeks 4 days or 4 weeks 6 days lol any input
