Welcome!
My DH and I also each have a 6 year old (from previous relationships)
We started TTC in October 2007 but also took a *break* in June, July and August....and prevented...so technically we are on cycle #10. But we started trying a year ago!
I'm not sure what's taking so long, either.
As far as your first doctor visit--are you talking about an RE or an OBGYN?
I had my first appt. with the RE last month and this is what happened at my first appt: he went over my temping charts, then I had a transvaginal u/s...I think the u/s was just lucky, though, because I just happened to be on CD14 and he wanted to see my ovaries to see if ovulation was gearing up or had happened. If I hadn't been in the middle of my cycle, I'm not sure he would have done that.
Then he looked all around with the u/s at my ovaries, and uterus.
Took a post-coital CM sample since DH and I had BD the night before.
Ordered 7 dpo bloodwork which checks progesterone level.
Ordered a semen analysis for my DH.
Then I started AF a couple weeks later and the RE ordered CD3 bloodwork.
I have an HSG scheduled today.
So---that's how my first month of being treated by an RE has gone!
Best of luck to you and WELCOME, this is a great board!
