Had my blood tests results back and I have extremely low B12 and folate levels. I have been told I need to start receiving B12 injections as well as upping folic acid.. gynae said to discuss the effects this will have on ttc at next appointment in 2 weeks. I googled and have read about low levels causing unexplained infertility, birth defects, miscarriage.. Probably all worst case but does anyone have any experience with this?
