I'm think I'm in Stage IV, but I skipped over OPKs and went straight to my doctor after two 65+ day cycles in a row. Haven't had to submit to an HSG yet, since my problem seems to be more of the uncooperative ovary variety than the blocked tubes variety, but I guess we'll have to see what the specialist says. Hubby did his SA this morning, so we'll probably get his results about the same time as the rest of my results come in. Then it's off to the specialist. Yippee.
I'm curious to know where my readers fall in the stages, so please de-lurk and share. :)
