Well, if it's any consolation, I'm the same. I'm about 14 weeks (?, you see I'm so on top of this, I don't even follow that very closely...) and yesterday, visiting my hubby in hospital, friend asks, 'And how is the baby.' Me, 'Well, I suppose it's fine, it never talks at me. I regularly talk to it, but it never talks back...' I mean, question was well-meant, but it's also a silly question, because I can't look inside myself and at the moment I can't even feel it move (yet), so how am I supposed to be able to know how things are? I mean, I have a modest bump now, so I can tell it's grown, but other than that, I can't really say until Monday when I've got an appointment at the gynaecologist and probably a scan.
Out of caution, I didn't dare to be excited or happy before this time, because you never know what happens. Besides, I was feeling too rough for that to be wonderful and exciting, really.
Fortunately I don't have a MIL anymore, so she can't bug me about this (although I doubt she would have done at that), but if she were, there would be a few more sarcastic/ironic replies, I can tell you. In such situations I sometimes wonder who is the mum-to-be, really.
