My belly is getting bigger now (28 weeks) and sleeping is becoming uncomfortable. My MIL keeps telling me one side is better than other. Want to know what you all actually do at night?
Left side they say, but my body has other plans at 3 am yaar. I just wedge a pillow everywhere and pray. As long as you mostly favour the left, dont stress about perfect positions.
My gynac told me the left side is best, especially later on, as it improves blood flow to the baby. A pillow between the knees made it comfy for me. If you roll to the right sometimes its okay, just avoid lying flat on the back in late pregnancy.
