My blood work showed normal prolactin level of 28. i have been breastfeeding only twice a day & my baby is 11 months old. should i expect my period to start soon with a normal prolactin or is prolactin not responsible for period during breastfeeding?

Some basics:: Elevated level of prolactin in nursing women suppresses the secretion of estrogen and progesterone resulting in amenorrhea. Your prolactin level is a bit higher than that of non pregnant woman (normal: below 25 ng/dl), probably related to intermittent breastfeeding. Once the level drops below 25, normal uterine cycle is likely to resume soon after.
