Moving toward some answers!
I had my first consultation with my doctor (actually his nurse) on Thursday, and I feel so much better about this whole TTC process now that we're taking some action. She looked at my charts and said that since I was very regular and obviously ovulating we could rule out a few of the blood tests, but she was a bit concerned that my LP is only 12 days long even supplementing with B6, so I have to have a progesterone test on CD 21. DH is scheduled for his SA on Tuesday, and we'll be able to get the results that same day. If everything is okay with him, the next step is the HSG. I'm so happy that we're moving so quickly toward some answers. I feel like a huge burden has been lifted! Any positive vibes you could send us would be much appreciated:)
