My wife and I tried in February with donor 15130, but because our doctor was out of town on the days I should have "peaked", we did the procedure on my first "high" day. There was still a chance it would work, and we didn't want to waste a vial and not do the insemination at all. But it wasn't successful.
My doctor thought we should wait until the following cycle, and track our current cycle again to get a more clear picture of my most fertile days. So we tracked March's cycle, and as I suspected I ran like clockwork!
April 24th I ordered my second vial. Since my "peak" day fell on a weekend, the office was closed, so I saw the on-call doctor. Best thing I could have asked for! Since the office was closed, the doctor met us outside by our car and walked us into the building. We were the only 3 people in the entire building, so it was a more personal and relaxed experience. There weren't other patients needing her attention, or any other distractions, which made me feel more at ease. I probably would have switched to using her as my doctor, but she is currently pregnant herself, so she wouldn't be available after August. She did tell me that she is a good luck charm, though. And I have to believe her now!
May 11th (two days before Mother's Day!) I got my BFP! I had planned a cute way to tell my wife that I was pregnant, and had a gift for her in the closet for when it happened. But when I got my positive test, I walked out of the bathroom shaking and walked right up to her in the kitchen. It wasn't the way I planned on telling her, but it was still the most perfect moment, we both just started crying. "Should we do one more, just in case?" Yep...still positive! 
Now I am 5 weeks and 5 days along! Wish me luck!
