I'm CD 18, waiting to O! In the past I've O'd on CD 19 or 20, very late in the cycle. My OPK came out negative this morning so I'm not sure that I will O on 50mg of clomid. Tomorrow I'm supposed to go in for a follicle scan and if they look good I'll get a shot of Novarel. From what I understand this will force me to O. DH and I have been BDing every other night just in case. We'll start every night for the next few nights in hopes that something will happen. My DR didn't say anything about IUI this cycle, but maybe next cycle.
I can completely understand the frustration of those in the 2ww, I'm not even there yet! Wish me luck on my scan tomorrow, I'll probably not post again until Monday after the scan to let you all know what's going on.
