11weeks plus pregnant

Sleep on left side is best. But at 11 weeks+, baby not heavy enough to compress the main vein and artery when you on back. Our gynae told us most important is actually the mummy gets rest. Position is good if can, but if mummy doesn't get sufficient rest, baby development may be affected. So, just get comfortable and don't stress about sleep position :) My wife slept on back most of the time in 3rd tri then in last few weeks, prop herself up using pillows as if in a recliner chair. She tried sleeping on side but always roll to back in middle of sleep. Baby is doing very well now.
