Thread: Rh-negative and pregnant

After discovering I was Rh-negative during my first pregnancy, I was worried and confused. So here is a quick explanation of what it is, and why it is nothing to be worried about.

During your first trimester, you will have some blood work done, and if your results come back that you are Rh-negative it means that you are a rare bird, because 85% of people are Rh-positive.

So it is more than likely your baby is in the 85 percentile of people because the father could have passed on the Rh-positive gene to your baby.

So, when you are 28 weeks, you will get an injection of Rh immunoglobin and this will prevent your blood from attacking the different blood of your Rh positive baby. Your blood will only mix with the blood of your baby during childbirth, or if there is any other complications. So, your baby will remain isolated in a safe little cocoon until labor time.

If you have any questions about my experience, please post away!

This is a great explanation of Rh factor. It's a really hard concept to figure out and wrap our brains around, and you've made it into simpler terms. Thank you for sharing your knowledge!

Thanks Pat,
It took two pregnancies for me to finally get it, it is difficult to wrap the brain around (;

Thanks for the info... i didnt know that!

I am Rh-negative. I had to get my shot at 28 weeks & I carry a little card that I have to take with me when I go into labor & delivery so the nurses & doctors know I am Rh-negative.
