Scarlet- 6 eggs is perfect for quality over quantity , my 2nd stim I had 6 eggs collected & we got 3 good blasties. My 3rd stim (for CGH) I had 13 eggs and still ended up with 3 good blasties. All those extra eggs didn't translate into better embie numbers. Oh thats very sad about your friend getting the BFN , a shame the immune issues weren't found earlier. I've already had the advanced tests for clotting factors & auto-immunity. I do have high thyroid antibodies, but all else was clear. I'm taking clexane & prednisolone for the TWW, and if BFP, will keep going til 12 wks. Its still too early for HPTs so I'm not thinking about it now. However, once I hit 7-8dpt, I get HPT fever and always cave in... hoping I can stay strong this time!
