I know there have been a lot of these threads recently (or maybe it just seems like it to me, because I'm so interested) but I wondered what everyone thinks from these scan photos - I don't even think I can see a nub! (but then I am rubbish at this sort of thing)
I didn't post on one of the other threads because I didn't want to hijack someone else's thread, but if anyone else would like to post their picture on the thread for wise Mumsnetters to guess then feel free.
Then we could all come back when we find out and see how accurate the Mumsnet collective are!
