I'm 5 weeks pregnant with baby no 2. My first pregnancy was perfectly healthy. Other than hypermesis, everything was great. Now my husband and I found out I'm pregnant with another baby and we are so excited. I'm RH neg and he's RH pos, that has me completely worried this time around and I have no idea why. I had my shot so everything should be fine. I have never miscarried before but I am paranoid that I will miscarry. It's to the point where I don't show my excitement to anybody, even him. Am I just being paranoid or is this normal for some people?
