Not emotional about much?

Ok so I am 15 weeks and I don't really seem to get emotional about anything  I'm my normal self. Only time I really show emotion is if I'm at drs hearing heart beat or there for the ultra sound. Is this normal?? For example my poor rabbit of five years died the other day and I didn't even cry and he was a big part of me and my fiancées life we've had him since we were in high school and first got together.. Is anyone else just perfectly fine? Or am I crazy
