Thought I was 7w4d doctor says I'm 6w2d

Anyone else have a difference of more than 5 days for their EDD after their first ultrasound?

I used ovulation tests and mucus to pinpoint my ovulation date. My doctor said sometimes those tests are off, and I must have ovulated late. Then I thought about how I got my BFP 9 dpo. If I did ovulate late, then how could I have seen a very solid positive less than 9 days dpo? 🤔
