Gods Plan Not Mine

After my last MC, it took a little while for my HCG to go down and things were on hold until we were able to determine if it would occur naturally. At my last RE appt, they did the b/w and the Doc gave me the prescription for the rest (which I felt was optimistic!) Well the next day I got a call from the nurse and she said HCG was negative and to go get the b/w done and call to schedule an appt once AF arrived. So AF arrived and I called and told the woman who answered that I was told to call and make an appt. She asked me what cycle I was on, which confused the heck out of me and so I explained this was not IVF and I was seeing the RE for recurrent miscarriage. Assuming that she understood, I went to the appt she scheduled for me today at 8:45am (thankfully I happened to have the day off or really woulda been ticked). So my mom comes with me and we get called in to the sono room and the lady asked what day and I say CD 2 and she looks at me all confused and goes to talk to the Doc. We then get called in to see him and he says he is going to do a saline sono but can't do that until AF is over!!! Then I think well at least I can get my b/w results.....but nooooo those aren't in!!! I did them over a week ago!! So why am I there??? I believe I did a VERY thorough job explaining to the woman who scheduled the appt because I got the impression she was confused. So basically I woke up crazy early on my day off and drove a half hour to an appt that wasn't even necessary! I go back on Thurs for the saline sono. I do have a question however. I am all new to this and am not sure what steps other women have taken. What is the CD 3 b/w? Because that would be tomorrow and the Doc has said nothing about it. Maybe I'm not asking the Doc enough questions. Any help would be greatly appreciated.

On a completely different note. I have been reading other women's blogs ever since I lost the 2nd baby and had always considered starting my own. Needless to say I am thrilled that I did!! This outlet has been so incredibly uplifting for me!! Not just have I been able to express myself to people who actually understand, but the encouragement I've recieved in such a short time is just amazing!! There are some truly wonderful strong women on here and I am so thankful for them. What a blessing!!
