Do not mess with anaemia. Contact the surgery as soon as possible. The failure of DD's GP to order a blood test, for a problem where a blood test is the first thing you get done nearly killed her.
By the time, 4 months later, she had the test, she was so anaemic, she was on the verge of death. her GP rang her in a panic saying she could have a fatal heart attack at any moment and sending her straight to the chemist to collect an iron prescription that was so large the pharmacist rang the surgery to check that it was correct. It was during lockdown, otherwise she would have been in hospital having blood transfusions and iron infusions.
