Hi, Both folvit and fertisure F will provide vitamin and micro nutrient required in pregnancy. It will help to become pregnant, form quality egg, maintain reproductive health and weight, decrease insulin resistance. If your period is not regular then following drugs will be useful after complete evaluation like reproductive hormone analysis, USg\G scan and ovarian follicle study. Clomiphene for maturation of follicle, progesterone in second half of period to support implantation and pregnancy. Metformin for induction of ovulation and insulin resistance. Avoid stress, Do sex in fertile phase of period, drink plenty of water, maintain proper pelvic hygiene and do regular exercise. All the best. Hope this may help you. Contact further if follow up needed. Best regards, Dr. Sagar
