Vit B 12 and Vit D deficiency with PCOD.

Since my first menstrual cycle, I had irregular periods. But during last three years, the problems have increased like the lower abdomen pain during the delay period as pre menstrual cramps. The cramps would be less painful during the periods but due to the bloating, the flow has been not good. I sneeze a lot when the blockage happens and then the flow will be released with lumps. The stamina, resistance to infections, immunity, memory, etc have decreased with time with increase in headache (resulting in Migraine), nausea, restlessness, bad mood, anxiety, and backpain. The digestion has also been an issue during last three years as I travelled two years to few cities which lead to stomach infections which took more than a year to reduce the problem of digestion. Still the problem exists and this time I got the results of the tests and I am attaching them here. Vit D25 hydroxy is 41.26 nmol/L. Looking into all my problems, Please let me know natural solutions and vitamin supplements.
