Can i lay on my back while sleeping i'm seven n a half months pregnant?

Yes: Women often ask this question.... what happens if I wake up and I'm on back in the latter months of pregnancy.Nothing bad will happen. There can be compression by heavy uterus on the venous return on right side... you might notice some edema or swelling, but no harm. Most women are uncomfortable flat on their backs at this point. Consider using pillows to prop yourself up so at an angle .
