Worried about lack of symptoms.

I'm 4w 6d, and this is my second pregnancy. I lost my first at 7 weeks in October. In addition to the normal fears that come with being pregnant after a miscarriage, I have zero symptoms this round. Last time I had the crazy fatigue and couldn't seem to stop napping but this time I really just feel like my normal self. I'd like to be able to accept and enjoy it, but I'm worried that no sore boobs, no morning sickness, and no fatigue are a bad sign.

Has anyone here had a healthful successful pregnancy without these things??
