Pregnant with my rainbow baby

I’m currently pregnant with my rainbow baby. I’m 4 weeks and 5 days. I MC in October, I was 5 weeks and 2 days. I can’t stop stressing and thinking about my previous loss, especially because I’m getting close to the time I lost my previous baby.

This time I don’t have many pregnancy symptoms at all. The only symptom I have is slightly sore breasts (which just started yesterday), but they aren’t too sore. Last time, I couldn’t even hug my husband, any touch was excruciating.

Last time, I had a lot of symptoms: Horrible nausea, food aversions (I couldn’t eat almost anything without feeling completely full and sick). The symptoms started very early. This time I don’t really feel anything at all. I’m worried as to why I’m not feeling any pregnancy symptoms with this pregnancy. Is this normal?
