High rdw cv, 7 weeks pregnant. Report!

Hi, I've got my anc profile that has low mchc but rdw cv and rdw sd higher than the reference values while my haemoglobin is 12.7. I lead a very healthy lifestyle with regular strength training and cardio and I avoid fried and junk food. I'm worried for what could have caused this. Some articles indicate a deficiency of folate, iron or vit b12 but I'm taking folvite since last 10 days. Since folic acid is important for the development of the baby's cns , I'm dead worried and want to know how can i make it alright. Because of my age and my father's medical history of by pass surgery, my doctor has prescribed heparin injection in the stomach everyday. I'm having those too since last 4 days. Please let me know what can i do to bring these values to normal. Attached is my report
