Super worried!

Shellie • 29 years old. Mother to 7 yr old twin girls and 3 yr old boy. Married 9 years. Pregnant with our rainbow baby!
So my only symptoms the whole time with this pregnancy, 10+5 weeks, is super fatigue and very occasional nausea. With my twins and my son I had horrible nausea the first trimester, and with the twins I vomited every day. With 2 previous MCs I'm so scared this baby isn't going to make it!!
