Interracial couple becoming scared of pregnancy

Ok so I'm newly married to my husband who is African American and I'm Hispanic (mexican). Well I have a daughter from a previous relationship and my hubby has no kids. We are at a point in our marriage where we have decided to start trying for a baby. I was so excited but recently with all this that's happening in the news it's just scary. I told him how I feel and he just says that it's gonna be ok don't worry. I can't stop worrying. I mean don't get me wrong I've had my fair share of race issues but this is beyond. I'm scared for him and for my unborn child. I just feel bad for not being excited anymore and he is so so happy that we are trying. How can I fix this?
