Good luck alicatt! I was also told 50%. I hate that. Kind of like tossing an expensive coin, isn't it? When is your OTD?
I know, it truly is the most expensive coin I've ever tossed! I'm not sure what OTD is? Is that the day they test your blood for hCG? If so, they have me down for Oct 1st, but I think that is WAY too late! My ER was on Sept 14th so 14 days from then is Sept 28th, and usually they test at 12 DPO (at least for IUIs they do). So I'm not sure why we are waiting so long.
I have been testing at home with HPTs to ensure that my trigger is gone. It seems to still show up on the ICs but it is totally gone on the FRER I tested with this morning. I'm going to hold off testing again until Sunday I think, as that would give the little beans a few days to start producing hCG.
