That is perfectly normal. You are just not feeling the symptoms of pregnancy as badly anymore and your hormones are leveling off. That is great news. I would say as long as you don't have heavy cramping and bleeding to try not to worry. More then likely everything is normal and healthy.
I know exactly how you feel . I was also in a similar situation . All my symptoms disappeared at about 8 weeks, and I worried like mad.It's perfectly normal to feel this way .
I never had pregnancy symptoms until I started to show/feel her move. Everyone is different, but if you're that worried, call and go in for some blood work
