Is O-negative safe in pregnancy with an O-positive partner?

Question

Hello doctor,

I am a female with an O-negative blood group, and my partner is O-positive. I would like to know if I can have a safe pregnancy and whether there could be any complications.

Additionally, if I were to have twins, would it still be considered a healthy pregnancy?

Kindly assist.

Thank you.

Hello,

Welcome to icliniq.com.

I am very sorry about your medical condition, and I am glad that you are paying attention to changes in your body. Do not worry. I am here to take care of you. I am really glad you asked this question. It is an important and very responsible one. Since you are O-negative and your partner is O-positive, there is something called Rh incompatibility that might occur during pregnancy.

Here is a simple breakdown: Your blood type is O (the "O" refers to your ABO blood group), and you are Rh-negative (meaning you do not have the Rhesus factor protein on your red blood cells). Your partner is Rh-positive, so there is a possibility that your baby or babies, if you have twins, could inherit the Rh-positive factor from him.

If an Rh-negative mother carries an Rh-positive baby, her immune system can sometimes recognize the baby’s blood as "foreign" and start producing antibodies against it. However, there is good news: modern medicine manages this situation very effectively.

Around 28 weeks of pregnancy (and sometimes again after delivery), you would typically receive an injection called Rhogam (generic name: anti-D immunoglobulin). This injection prevents your immune system from developing antibodies that could harm the baby or future pregnancies.

I hope this helps.

Thank you.
