I had a good uneventful journey home. My lovely friend picked me up from the airport. It was so nice to see a friendly face!
I have to admit that I'm still feeling bleak today. Rather than try to squash the feelings I'm going to trust that it'll run its course. I think it's self preservation - expect things not to go well and anything better will be a nice surprise. I've got nice plans for the weekend so hopefully that'll cheer me up a bit.
Stork if I were you I'd get some hormone blood tests to check your levels. Your GP might be willing to run these. Then you'll know better where you are. If they're out of balance (I think it's that if one of the other ones is high then it can inhibit LH). The other thing to say is that there are people who don't get on well with OPKs. A friend of mine stopped using OPKs after not being able to track the surge and is now pregnant with her second child.
Also, as Kwick says, get a scan at around CD10 just to check that you are growing good follicles. This might put your mind at rest.
What time of day are you testing? It is really important to test multiple times a day around the right time (use the internet cheapies until the line starts to get fairly dark - otherwise you'll bankrupt yourself if you use lots of ClearBlues!). For example, before the miscarriage I always got my surge at 8pm, which is very late in the day. If I had only ever been testing at 10am I probably wouldn't have picked up the surge.
