Decrease in symptoms isn't a sign of anything worrisome. Now if you start bleeding or having severe pain especially on one side of you abdomen I would go to the Dr. But as is, your body is probably just adjusting to the hormones and is handling them better than before.
Lucky you. Enjoy it while you can :) Good luck
Pregnancy is a wild ride and each one is different. Try not to worry and enjoy the days in which you are feeling good!
I had a few at the beginning then stopped around 6 weeks. Now I'm 19 weeks 4 days with a boy and bam symptoms are back for a while with a vengeance.
I don't have pregnancy symptoms I can eat whatever I want
