If you have ever been pregnant, you've probably asked yourself what you can and can't do. Is cooked sushi OK? How much coffee is... too much coffee? And quite possibly, can you donate blood when pregnant?

While we may not be the best place to answer your sushi- or caffeine-related queries, we're happy to guide you on what we know best: blood donation! So whether you're expecting, expecting to be expecting, or are just generally curious, review the sections below to have your pregnancy blood donation questions answered. Wondering whether breastfeeding mothers can give blood? We've got you covered, too.

So... Can You Donate Blood While Pregnant?

Unfortunately, the short answer is no. Women are not eligible to give blood during pregnancy. Here's why:

Increased Iron Needs

During pregnancy, a woman's body requires more iron to support both her health and the developing baby. Blood donation removes red blood cells from the body, which can lower iron levels. This could lead to iron deficiency anemia, which may pose risks to both mother and fetus.

Blood Volume Changes

Pregnant women experience a significant increase in blood volume. While this may seem like an advantage for blood donation, the reality is that this extra blood volume is crucial for supporting fetal growth and the changes taking place in the mother's body. Losing blood during donation could strain this delicate balance.

Help! I Accidentally Donated Blood While Pregnant!

Did you give blood before you knew you were pregnant? That's OK. Each time you donate at Our Blood Institute, we check your hemoglobin levels and other health indicators to make sure you're able to safely donate. Still, we recommend you let your doctor know that you gave blood.

I'm Taking Infertility Shots. Can I Give?

Yes! Infertility shots will not interfere with your blood donation, provided you are not pregnant.

Can You Donate Blood While Breastfeeding?

Eager to return to blood donation after giving birth? We appreciate you! Before you do, though, here are some key points to know:

  • Six-week Postpartum Wait: The same six-week deferral applies to breastfeeding and non-breastfeeding mothers alike. This allows your body time to recover from childbirth and restore healthy iron levels and blood volume. This waiting period is important to ensure that both you and your baby are well-supported!
  • Maintaining Health: When breastfeeding, your body continues to demand extra energy and nutrients. While donating blood after six weeks postpartum is generally safe, it is essential to monitor your own health. Donating blood while breastfeeding can slightly lower your iron levels, so it's crucial to maintain a balanced diet rich in iron and other nutrients to support both lactation and recovery.
  • Consult Your Healthcare Provider: If you're unsure about your readiness to donate after pregnancy, it’s always a good idea to consult your doctor. They can assess your current health, iron levels, and general well-being, providing personalized guidance on whether it's the right time for you to donate.

Blood Transfusions in Childbirth Are on the Rise.

Between 2006 and 2015, the rate of transfusions needed in childbirth in the U.S. increased by 54%. Now, transfusions are required in one out of every 83 deliveries.
