@wowweddings20000: Okay, I hope what I say doesn’t discourage you or your daughter, but I’ll put it out there as a reality of what can happen.
Three months ago my husband and I ventured onto our first IUI round with Clomid, FSH injections, trigger, etc. That cycle ran smoothly, at my cd11 u/s I had an 18mm follie that looked good but they wanted to wait one more day before I triggered for it to grow to a 20 (they grow on average of 2mm a day). Well, long story short I triggered and had the IUI, but BFN.
Two months ago, IUI cycle #2. They changed my protocol by increasing my Clomid and FSH dosage. On CD11 I didn’t have any follies over 11 (Also, at my clinic, if they are under 10 they don’t even measure, so that might be why they didn’t give her a size). I was told to go home and do more FSH injections. Next u/s, same thing, they didn’t grow at all! Again more FSH injection, u/s, no growth. I was devastated. We had to go out of town for a family function and when I came back my follies were gone without ovulation (basically, they shrunk back down)! I was even more devastated, but mostly confused. How could this cycle be so different when the 1st one worked perfectly (well almost)? Well, I asked my nurse and as others above have said, every cycle is different. I know, that’s something we don’t want to hear and it doesn’t really help us truly understand why.
My theory: I have been diagnosed with PCOS. I feel I have one polycystic ovary that is really lazy and one that’s just mildly lazy. The first cycle I know I O’d from the not so lazy one because obviously that’s where my follie was. This past cycle I feel confident in saying my body was trying to O from my lazy one. Sorry for lack of better words here, but I’m sure you get the point.
But, just because mine never grew and “disappeared” doesn’t mean that will happen with your daughter. Every cycle is different and they just might be moving slowly. Is your daughter seeing an RE? If so, ask them about trying injectable FSH, it’s “supposed” to make them grow faster. Regarding the lining, because of the slow growth in the follicles, it might be developing slowly, which is a good thing. You don’t want her lining to build thick by time she has matured follies.
There is still hope, just keep faith. Good luck to you and your daughter. I think it’s a great thing what you’re doing and that you understand what she’s going through.
