Thank you all so much for the congratulations and for being so lovely. I truly understand how hard it is for some of you, so it just makes your kind words all the more thoughtful. I never thought it'd be my turn and am still waiting for it all to go horribly wrong!
If nobody minds, I'd like to stick around for a bit and see if I can't offer bits of advice here and there that I've picked up over my ridiculously long TTC journey. I know I wasn't a Clomid buddy for very long, but I don't feel as if I'm remotely safe yet and I also want to be able to congratulate everyone here WHEN you all get your BFPs. It WILL happen. I've put a Karmic order in. 
grumpy I've heard that OPKs can be a bit out on Clomid too. I guess it largely depends on how high a dose you are on, but I was advised that provided you don't use them until at least 3 days after you finish the course of tablets that month, they shouldn't interfere. This may present problems for women who ovulate early and, obviously, there are always ladies out there who they don't work for regardless of ovulation, which just adds further fuel to the fire. Oddly enough, they did work for me this month. I found them quite useful in terms of correlating fertility signs and doing a bit for myself without the doctor's interference, but, like everything else, they aren't 100% accurate all of the time.
I have eyes, fingers and toes crossed that this is your month.
confu3ed so sorry about your blood test. I would have been fuming. This is hard enough without the added annoyance of them not doing their job properly. FWIW, it is absolutely possible to get a positive OPK two days running and it's quite comforting that you get such a good warning! A positive OPK signifies that you're going to ovulate sometime within the next 12-48 hours, so get SWI as soon as you get the first one and hopefully, that should do the trick.
MissFlick That all sounds really positive and I'm impressed that they are giving you progesterone as opposed to just telling you you're out for this month because of low levels. Can I ask, did they tell you a number for your level of ovulation? They don't tend to be very forthcoming with this information (in case you start reading about it and self-diagnosing!), but I doubt they would have bothered with the progesterone unless they thought you were in with a fighting chance, so I have everything crossed for you.
Lady How did your scan go?
Waves (and thanks) to boba, popsy, nonu, highheels and stac and anyone else I may have missed.
