Well good luck with the SWI. 
We weren't going to be monitored either. I guess if it just makes the ovaries work a bit harder then if you were already ovulating, you still should. You just might be on the for the second lot of Brooking twins 
!
Our consultant though reckoned that some studies had shown that even for people without an ovulation problem the chances could be increased. I have to say that I wasn't necessarily convinced by it all but was willing to give it a go. I wonder if Clomid actually helps with some 'other' problem which they haven't quite established yet, but equally which hasn't been diagnosed. I'm not explaining this clearly, sorry. I think when they say 'unexplained' what it really means is 'undiagnosed' There must be a (or some) problem(s) but it is just that they haven't worked out what it is because it isn't covered by the scientific tests.
So I wonder if perhaps Clomid helps with some of these unexplained problems (maybe without the doctors even really knowing what the problems might be?) and that could be why it might increase your chances even though there is no ovulation problem?
Sorry, that's an awful explanation. 
I know I felt a bit like it was a stab in the dark for us - like it might help or might do nothing but no-one really knew which - it didn't feel very diagnostic to me? I would have preferred them to say 'This is the problem and therefore Clomid is the solution' rather than 'erm, well Clomid might work? Who knows....'
Anyway, I'm very much hoping that it does do the trick for you Solars. Did you say you were going to monitor ovulation this month? I think aiming for a good range of days is very sensible.
Sorry if that doesn't sound very positive - it isn't meant to be negative about Clomid - heck anything that might improve things is worth a go I think?
