I know it's easier said than done, but try not to read *too* much into your chart. You may have a beautiful triphasic chart which results in AF, or you could have an ugly riding-the-coverline chart and have it end in a BFP... Unfortunately, I've seen some VERY pretty charts from ladies in here (and my own when I first started Clomid) that just didn't matter.
As for your chart, I wouldn't necessarily say you have a dip yet... your temps look good though, and as long as they stay above the coverline I wouldn't lose hope. I'm hoping for a good result for you!

Has the HCG come out of your system yet?
Edited to add-- I'd call today's temp more of a "dip" if your temp spikes back up tomorrow.
