6w3d but ovulated late...

Jessizu • I wear lots of hats.
I ovulated on CD 18... Does that mean im more like 5w5d?... Got a strong positive on 10 dpo... My first ultrasound is on friday... Cant wait to see my . little one but i was trying not to get my hopes too hugh and expect to see an almost 7 weeks old baby verses a barely 6w... Thoughts? Any experiences here?
