Well it looks like you O'd on the 18 so I'm guessing right around there?<br><br>
Maybe I'm not understand the question. <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/lol.gif" style="border:0px solid;" title="lol">
Your chart seems so obvious about O'ing on CD 18. Can ultrasounds be off by a few days? That's what, a 5 day difference? I'd be more inclined to trust my chart since babies develop at different rates.<br><br>
If you ovulated on day 14/15 that would give you a DD of 12/6. Looking at your last month I would have to say that is where I would put you. It seems that day 17 is totally messing with FF. Have you tried taking out 17 and possibly 18 to see what it does?

<div style="font-style:italic;">Was 12DPO the 1st day you tested?</div>
Yep. It was a digital test and must have been pretty sensitive, because then I used a dollar tree test the next day and got nothing.
How does your intercourse pattern line up with this? It's not showing on your chart.<br><br>
But, I'd say you O'd on CD 15 instead of 18.<br><br>
ETA: Here's my chart <a href="http://www.fertilityfriend.com/home/mama2many" target="_blank"><img alt="" class="inlineimg" src="/img/vbsmilies/smilies/BFPChart2.gif" style="border:0px solid;" title="Chart"></a> - totally crazy I got pregnant. The spotting from March 31 - April 6 was heavy, just like a period!
