Do pregnancy hormones make you less fearful? As I've got older, I got a lot more wimpy, and I would actually almost faint when the nurse took my blood. I had total anxiety about everything. Since I had my 12 week scan I have totally changed. I couldn't care less when they take my blood, I could let them do it all day, and I actually feel really defiant about giving birth now too! almost as though I'm looking forward to battling the pain, I just feel like 'bring it on!', is this normal? or does anyone feel frightened about giving birth etc?
