3 doctors weighed in: When during pregnancy should you stop laying on your back? 3 doctors weighed in Want a second opinion? At approximately 24 weeks you should avoid laying on your back for prolonged periods of time in order to avoid compression of veins (vena cava). In brief: 6 months.
This is probably not significant until after about 16 weeks, however. An interesting study found that women slept as follows: Non-pregnant Pregnant Back 33% 34% Side 60% 65% Stomach 7% 1% before 16 weeks, 0% after 16 weeks This shows that women naturally will stop sleeping on their stomachs as their uterus grows.
