I'm definitely not going anywhere (I like it here!), but the u/s is actually probably right. My medicated cycles make it extremely difficult to pinpoint an o date because the clomid messes with my temps (a lot!) at the beginning of the cycle. Plus, the u/s puts me o-ing very close to my HSG, which makes sense because when they did it, they found a follicle that was over 2 cm. It was definitely ready to go! Personally, I thought the chart was wrong. But my OB's are good. They'd let me go a week without going nuts, especially with the initial confusion. Plus it makes sense with my pregnancy test. I got a dark positive at what I thought was 8 dpo - that seemed off to me. Now I know why it seems off.
