Resistant ovaries

So I had an u/s this morning. CD8 (last cycle was on CD7) and things are moving very slow. My lining was 4.7 (was 4.8 on CD7 last month) and my follicles were only 9.4, 8.3, 8.3, and 7.7. The others were 6.7 and under. Last month a day earlier they were 11.2, 11, 9.6, and 9.0. My estradiol was only 64 today, compared to 145 last month. We expected the low estradiol though since my follicles were smaller. The lining doesn’t bother me either, because I know we’ll have more days to stim. Kim just called and they’re bumping me up to 4 vials/day. So now I get a shot w/ 2 vials at 7am, and another with 2 vials at 7pm. Oh goody. She said that at this point we have to be more aggressive and hit it all hard. She said that we have to figure out something to do about my “resistant ovaries.” I’ll still do 3 vials tonight and start with the 4 tomorrow. I go back at 9am on Monday to see how we’re doing. Her concern is that with the 4 being semi close in size, all will take off. I have no idea what we’ll do then, but I don’t see that we have much choice at the moment. I was reading that you can stim for too long and it decreases the quality of the eggs – so that would be a possibility if we stayed at 3 vials. 4 vials we might have too many, who knows? I doubt it, but it’s a possibility. So the other option would be to cancel now, but that seems silly because we really don’t know what is going to happen. So I'm not sure if I'm depressed/anxious/optimistic/freaked out/etc by this news. I guess I just feel like we'll roll with it and see what happens.
