When Should You Start Prenatal Massage During Pregnancy? Most practitioners advise beginning prenatal massage in Singapore around week 13 or 14 of the second trimester. Due to the increased chance of miscarriage in the first trimester, many therapists advise waiting until the pregnancy is more stable. Regular sessions can safely reduce swelling, improve back discomfort, and promote emotional health starting in the second trimester.
