I still sleep on my back (usually wake up on my back) but no matter what side I sleep on I will get uncomfortable so I'm constantly changing positions

@keebs, yes! That’s what I do haha I end up being in a 45 degree angle with a pillow under my back

If you are in pain then move. Regardless of which side you are laying on. If it’s still comfortable to lay on back it should be fine. It doesn’t really become an issue for several more weeks because baby is so small. Just lean on your left side when possible to promote the good blood flow :)

As long as you're comfortable- baby is fine... The baby has so much fluid around it and extra cushion that it's fine... I know this because I was concerned when I was pregnant with my last baby and I asked the doctor and that's exactly what she told me...
