Just as the title says really.
I can't put my finger on it, I'm just terrified that something's going to go wrong. I'm not a first timer (far from it!) but I am a bit 'older' so this is probably the last baby I'll have.
It's just incredibly stressful and I didn't feel like this with any of my other pregnancies - even after the ones with poor outcomes. I'm almost in tears here just typing it (it seems more 'real' now it's out there).
Jings, flaming hormones...
