I don't know anything about temping MummyDonz, but are you going to have a follow up scan or are they just assuming you were about to ovulate? I've never seen mature follicles on a scan so I have no idea what the protocol is.
Well, I phoned the clinic today and they said no to a 7DPO blood test. Grrrr. So I'm going to have to hope that I ovulated and sit out the TWW....
