Rh Negative

I am almost 29 weeks and haven't gotten my Rhogam shot yet. I have to wait until my insurance approves me getting it. Will my baby be okay until I can get it as long as it it is before delivery? I am so worried and scared I hear so many mixed things about this. Some tell me it is fine as long as I have no bleeding but some say differently. Scared my baby will die. I got the shot when I miscarried my first baby.
