Feeling down

Nicole • Have a beautiful 1.5 year old boy 👶🏻 February 6th 2018👼🏻 . Twin boys due April/may 2019🌈🌈
Well today I'm 4 weeks and 3 days. Just having a super bad morning. Sometimes I read too much of the comments on this app and it scares me. This is my first pregnancy and I'm so excited but I don't want anything bad to happen to this little peanut. How does everyone stay positive and not think about miscarriages:(
