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. So, now that I'm cd2 again, I called my RE's office & asked the nurse to look back each month to see if my lining has always been thin... Even on the day of iui, it was only 5 point something! She said it's supposed to be 7 or 8. I'm sitting here waiting for a call back from my RE, but I've been waiting 2 hours... I'm thinking this could be why I'm not conceiving & I'm hoping there's something I can do to fix this. I take progesterone after I O, but is there something I can do to thicken my lining before I O? Thanks for any help!!! :)
