Hi Ms. Mehek,
It is good to see that you are so concerned and aware. The complexion of the baby is mostly determined genetically. Yet, it is often said that use of saffron is helpful, though there is no established scientific basis. A healthy baby can be had if you maintain adequate rest, healthy diet that includes fresh fruits, vegetables, sufficient liquids and protein, and avoid stressful activity and exposure to harmful agents. Please have regular follow up and also get fetal monitoring. If there is no objection by your consultant, you can do mild exercise like slow walking to facilitate vaginal delivery, though it can only be decided at the onset of labor. Wish you safe motherhood.
