Hmmmm. Not sure. If you go with the idea that you have a consistent temp rise of 3+ days then it looks right. O is also only a day different to your last cycle - were you taking Clomid then?

I had a temp dip just before my BFP - have a look at the second chart http://www.fertilityfriend.com/home/240d3b I did also have an implantation dip though at 6dpo. I really hope this is your month! If not though, get onto some decent OPKs quick smart!! Yes, that's an order
