Hi. Dh & I are in our 3rd year ttc. We both checked out okay, but so far, no luck. My only issue is that I have a t-shaped uterus & so my RE won't put me on meds that could increase the chance of multiples. It's too much of a risk. Anyway, this past cycle I had an u/s on cd12. My RE measured my uterine lining & I can't remember how thick it was, but she commented that it was thin, but that I had a few more days for it to thicken.
