I've heard some people have had different results at different clinics/with different FSs, but then again you may also get the same result.

Have all your 3 cycles been the same protocol? (eg down reg, flare, antag).

I've done 4 down reg cycle & haven't really responded with egg numbers. My next cycle is a flare, as my FS thinks the down reg may actually be putting my ovaries to sleep IYKWIM.

How many embryos have you transferred? There is always tests for recurrent implantation failure, that is normally done after 3/4 fresh cycles.

HTH & good luck
