littleerin I would def not use clomid bought over the Internet and yes you're meant to be monitored while you're on it. So I wouldn't do it because firstly you're not being monitored at all, and secondly how do you know the quality of the drug if you got it online? Do you live in the UK? You can get clomid free on the NHS.
littlemiss you sound like me with the swotting up, I'm a bit of a worrier so have done soooo much googling research! I don't think I ovulate naturally but I have PCOS so I think that's why. I was thinking the other day that I don't know for sure I don't ever ovulate naturally, but I've never had signs of ovulation, I have PCOS, no BFP after 13 months trying and my cycles are long and irregular, so based on that, I don't THINK I ovulate.
I tried to find stats the other day on whether clomid is more successful for certain things than others too! I think though, if you aren't ovulating and it makes you ovulate, then you just have the same chance of getting preggers each month as the average for people without ovulation issues. So at least you and I will be in with a chance each cycle! 
Goods luck with the HyCoSy, I was ridiculously nervous but so relieved when they didn't think they could see blocked tubes so could give me clomid. Really hope you follow exactly in my footsteps there!
On day 10 now and just dtd but I guess too early to be trying! One thing I did read, can't remember if it was on here or somewhere else, but it said the first cycle of clomid is just priming to system for ovulation, so it's more likely to lead to BFP in following months. Although some people do get BFP first time round! Would be amazing if that were me!
Wow sorry I'm rambling, better sign off
