TTC: 40, need advice on follicle size + IUI

[jessicadp]

Hi ladies,
I am 40 yrs old and TTC for 1 year. In Jan 15, I tried clomid + TI - had 5 follicles but didnt take, in Feb I tried letrozole and had 1 follicle @ 30mm and did an IUI which didn't take. In hindsight, I shouldnt have done that IUI and wasted my insurance coverage.
This month we upped the letrozole and went for U/S today (cd 10) and I have 1 large follicle @ 28 mm, and 1 @ 11 mm and another at 13mm. I took a trigger shot tonight and am supposed to do an IUI in the morning. My regular FS has been on vacation this week and the monitoring doctor says it;s up to me. Insurance wont cover this IUI. My instinct says to 28 is too big and the others too small.
My instincts say hold off a month and do TI again and hope for the best. Then discuss injectibles or move on to IVF.
Any advice? Or success stories with those sizes?
Thanks,
Jessica

The cycle that worked for me I had 2 follicles, 20mm and 23mm. Can you go back on the clomid since you had more follicles? Not sure what I'd do, but I'd probably follow the advice of the office this month and then either go back on clomid or start injectables the following month. Good Luck!!!!
