Hi, I understand your concern. Last time you had abortion in 2nd month of pregnancy. Abortions in early months of pregnancy are mostly due to hormonal deficiency ( Hormone Progesteron)which causes the pregnancy to be weak & abortion takes place. Now you are pregnant again, You must have done investigations after abortion. * - You should consult a gynecologist, show all the previous reports/ get few fresh ones done if so advised. - such patients are usually supplimented with hormone Progesteron ( injectable or oral ) It is continued without a break till 3.5 months. - continue with other vitamin supplimentsincluding folic acid, - Take rest/avoid physical or psychological stress./ minimum travelling. - Be positive These precaustions should continue your pregnancy normally. * Back ache here may come from calcium deficiency/ weak fetus tending to abort/ pelvic inflammations.The cause is investigated & treated specifically, * In pregnancy digestion is hampered due to pregnancy hormones. The solution lies in taking multiple small servings of food- intake of nutritious food ,& use of digestive enzymes as per your doctor s advise
