Each woman and each pregnancy are different, so there is no standard answer to this question. If you are planning to use massage therapy as an integral part of your prenatal care we suggest once a month in the first trimester, twice a month in the second and third. If you are having a difficult pregnancy with back pain, sharp leg and hip pains or sleeplessness LillieAnn's Massage & Skin Care recommends increasing your session to 90 minutes or coming once a week in the last trimester. LillieAnn's Massage & Skin Care is a certified prenatal spa in Chicago and they want to help you feel at ease during your pregnancy journey.
