peekay,
Regarding the OPKs I use Ovunow and I buy them online. There are also some OPKs from lullabyconceptions.com that are pretty cheap. I think I get 50 for about $40. And yep it was totally a guessing game. I did an OPK every day until I got a +ve. By the time O actually happened I'd gotten through a whole box! I'd not had very good cm observations the previous cycles but this cycle I'd had some ewcm and so was hopeful O was on its way. I then confirmed it with the temping. I've just started on Clomid now. My FS is monitoring me very closely due to the high risk multiple births and over stimulation of the ovaries. This is a matter definitely best handled by a specialist and not a GP...... Hang in there. The 13th Sept will be here before you know it!
