I'm so sorry. You're not out until AF though. How long have you guys been trying for #2?
campn I was in the same place, and was starting to worry that my tubes were blocked or that I had a fibroid (which I did, actually).
We had conceived the very first cycle with both DD and DS, but this time around cycle by cycle were going by with no BFP. We finally got very strict about scheduling, did both SMEP and Pre-Seed on cycle #5 and boom, pregnant. So if you haven't tried Pre-Seed or SMEP, I personally think they are a winning combo.
I totally understand your frustration
