I've only been trying for a couple weeks. Thanks for the advice! I guess im just worried that if I can't sleep on my side im going too end up hurting the baby. But I do feel better now!
How long have you been trying? I started sleeping on my side - which I've never done before - when I first found out at 4 weeks pregnant, and by the second trimester it was natural for me. I use body pillows too, and occasionally switch sides. The left side is ideal for circulation and all that, but switching to your other side is okay. It's okay if you wake up in another position, just roll yourself back to your side and go back to sleep.
