Girls, hello everyone. Yesterday I saw my doctor, I have low hemoglobin and ferritin is also low, they prescribed me to take "Fersiinol" and "Heferol" for a long time. The question is slightly different. At night I had bleeding from my nose profusely (noticed it in the morning). Throughout the day three times, it flows heavily, I just can't change the tissue, and stops for 10 minutes. My head hurts. I think this is directly related to low hemoglobin or could there be another reason? The blood pressure is normal. Has anyone experienced this? How dangerous is it for the baby? Thank you in advance for your answers!
