10 wks and lost all symptoms

Christy
I'm 10 weeks today with twins and suddenly, like overnight, my symptoms have vanished. It makes me so nervous. I have read it is normal bc the placenta is forming and takes over. But I would love to hear your own personal experiences on this. I had a MC oct 2015 and nov 2016 so I'm just anxious. 
Thanks in advance, ladies.
