Hmmm - DG and Olive - it sounds like you are saying that when we (myself included) were suggesting monitoring more closely, that it meant I automatically was saying that it would mean success. All of my cycles, transfers etc. were monitored (had to be ICSI with fresh transfers + FETs after ICSI - cycle after cycle, with repeated BFNs) - so I know that it doesn't necessarily mean a BFP ...
My point was only, that by monitoring when you do the IUI, you are going to be upping the chances of success (for example, to me, it seems pointless doing the IUI if ovulation hasn't been guaranteed or might not even have taken place - I never did an IUI, but I am sure that it involves spending money on the procedure ...)... and I see no harm in trying to increase the chances of something working.
There is never a guarantee with TTC. Neither for people able to conceive naturally, nor for those going through AI - in whichever shape or form it may happen. I too believed that first or second try would work for us ... and you know how many it ultimately took (and even now, I am in disbelief regarding my little miracle)...
And with each try we went through, there were people on my group saying "this is it, this will be it, this has to be it" and I did get tired of hearing it, because I stopped believing it ... just couldn't give up (but also said, that I couldn't hear it any more).
What I do believe in, is trying to do what we can to increase our chances and personally, I firmly believe that monitoring whether or not ovulation takes place
is important, to make sure that there is something there for the sperm to try to fertilise. Whether or not that then results in an embryo that nestles in ... that is a huge portion of luck, fate and everything else that gets thrown our way ... IMHO.
all around.
