first, try to get on medicaid. that's what i did..you may be denyed at first but keep trying. i was denyed twice before being accepted. I also have RH-negative blood and had to recieve the Rho-gam shot. you can check for clinics in your area online and call around to see if they give the shot. but if your pregnant you REALLY need to go to the doctors every month! otherwise there could be something wrong with your baby and you would never know it!! try
www.maternitycard.com its an insurance for pregnant women. for the sake of your baby, go to the doctor!!! also you dont need the shot until 28-32 weeks
