I'm with you. Had a MC in September and got pregnant in Oct. I'm RH negative as well. I have been so worried but finally have an ultrasound on Tuesday. I'm 10 weeks. Try not to stress.
They should give you the rhogam shot earlier this time, let your health care provider know ASAP the situation and you should be fine. Im negative blood type and my provider wont give me the shot til ny 3rd trimester. Me and baby have been doing really well so far, been a great carry. Im so sorry for your loss but hopefully they are aware mow and can help you and your little miracle :)
