I'm 11 weeks 4 days and ever since I found out there are 2 babies inside I have had this fear that I will lose one. We just announced to our family that we're pregnant and we're having twins. My sister was supposed to be a twin so I asked my mom when she lost the other twin and she said 13 weeks. I am trying so hard not to worry but I can't help it. Anyone have similar family histories with happy endings?
