Hello! Most definately go to the doctor and get your shot! From personal experience as a RH Negative, I miscarried my first born right at 8 wks! I bled my whole pregnancy! The midwife never mentioned to me that this shot would save my childs life! I learned that by the time I recieved the shot it was too late! I woke up mothers day in my regular routine of being prego miserable and already started passing clots the size of marbles! I spent mothers day recieving a DNC. I beg you to please do your homework with this! To explain it in a shorter version than the Web; to my understanding, my husband has positive blood and because you don't know what the childs blood type will be when it's born, your body is doing a good job of acting as an antibody towards your child! If the babies blood is positive, your body is going to do it's best to get rid of that "foregin object". Now with that said, the doctor gives you the shot Rogham, to stop the fighting process! If your husband has negative blood as well as you, you are costal clear of any shots or complications associated with our blood type! I hope that helped you some! God bless and Mothers Day will come easier for me this year than the last! I am planning on trying again soon, now that I am aware of most all the risk!
