IUI -no surge

Hello all, not sure if anyone will know anything about this, but here it goes:
I am in a same-sex marriage and TTC. We did 3 IUI's and got pregnant on the 3rd. Unfortunately, we had a miscarriage at 11 weeks. I had to have a D&C in early May.
I have been anxiously waiting to get back in the game. I take letrazole each cycle and so far, that has done the trick. This cycle was my first cycle TTC after the miscarriage. I have been using opk's and typically surge on day 14 or 15. On day 15, all signs were pointing to surge. I use clear blue digital tests, and kept on getting negatives. I was testing every 4 hours! The lines got extremely close in darkness and I would have sworn they were positive, but digital reader kept saying negative. I then had strong cramps on the left side from 2pm until I fell asleep at 10pm. Everything seemed normal except the tests were negative. I called my clinic and they told me I could do the IUI if I wanted to. I decided to go ahead with the IUI because the cramps were so convincing. Anyone have any experience with having all signs of ovulation, but negative opk's? Trying to be optimistic and hoping I didn't just waste $1200 with no egg in there waiting for it.
