the grinch

Ok, thanks for the info! Do you remember have many mature follicles you had at the time? I usually only have 1-2 with clomid 100mg so he bumpimg me to 150mg to see if we csn get 3. My antra follicle count is only an 8 :/. I have too done the trigger shot :)

The first failed cycle produced one mature follicle at 23mm and one "kind of" mature follicle at 14 - highly unlikely to implant, but not impossible.  The second cycle produced two mature follicles, 24 mm and 18 mm.  I know from an early ultrasound that it was the 24 mm follicle which implanted.

The other thing I wanted to tell you is that clomid is known to decrease the endometrial lining thickness.  You really need a thickness of at least 7 mm for a successful implantation.  The first cycle my lining thickness was 8.5 and the second one was 7.75.  I've read on fertility boards that if you do 3 cycles in a row and still aren't pregnant, it's good to take a break from it for 3 - 4 months to let you lining recover so that it will get thicker.  If I remember right, it has to do with the extra estrogen that clomid helps to increase, whi*****reases ovulation, but decreases the endometrial lining thickness.

Wow! Thats huge!!! My RE likes to trigger at 18mm which haooens fairly quickly when I'm on clomid, around cd 10-12. They have also given my estrace to help combat the side effects of clomid. They have never said anything about my lining but I will be sure to ask next time I see them. Right now I am waiting on AF to start so I can start clomid on cd3. I havent taken clomid since october which is when I had my first IUI. Alot of times I have to take forced breaks bc I end up with residual follicles (cysts) when taking clomid. I will ask my RE if we can maybe wait til 20mm+ to trigger instead of 18mm. So my regimen will be 159mg clomid cd3-7 and estrace every day once I start clomid. Then afyer the iui we will do progesterone :)

Best of luck!!
