Yes: Average lifespan of red blood cell is 90d so any nutritional deficiency affecting rbc size should show up after 7 months.

Yes: Are you saying that your hemoglobin dropped to the anemia range? Nutritional anemias can pop up fast, or there may be another cause. All anemias are serious, and need to have a cause found. I hope that your diet did not make you deficient in one of the nutrients that you need -- it's best to work with your physician on this when you start. Hope the cause is found soon.
