A hemoglobin level of 7.5 at 32 weeks pregnant may indicate iron deficiency anemia, which is relatively common during pregnancy. However, it is important to address this issue to ensure the well-being of both you and your baby. Iron injections are often recommended to increase hemoglobin levels and prevent complications such as preterm birth or low birth weight. It is advisable to consult with your healthcare provider for further evaluation and guidance on managing your iron levels during pregnancy. They may also suggest dietary changes or additional supplements to support healthy iron levels.
