Throughout my pregnancy I have been spotting, doc says its due to a subcronic hematoma as well as a abrasion on my cervix.. As a cherry on top I am RH negative. When I first spotted some spotting I went to the ER they have me a shot of a blood product that lasts 12 weeks... The 12 weeks is over and I am continuing to spot. My doc says not to come in for another shot, but when I saw a nurse practitioner she said to come in and they would give me the shot. This is all making me so crazy, I don't know what to do or who's advice to take. I have made an apportionment with my doc tomorrow.. I'm afraid he will not give me the shot..
