Last night was horrible.

I couldn't sleep at all, every position was very painful. If I lay on my left side, I get a sharp pain up near my ribs. Doctors usually tell you to lay on your left side to help with circulation, but it hurts me. I can't lay on my back cause I can't breathe, I literally feel like I'm chocking. Then if I lay on my right side my back gets a sharp pain in it, and my right arm goes numb. Nothing is comfortable, NOTHING! I kept waking up every 20 minutes, I felt like I was going to cry a few times, I was just so frustrated. I feel like my body isn't made for twins, but thank god I'm towards the end, kinda. 10 weeks or less away. I'll be 35 weeks September 3rd and 37 weeks September 17th, and twins are usually born around 35 to 37 weeks. I keep having dreams about the number 13, so maybe September 13th, which is weird cause its in the middle of the 35th and 37th week. I just hope it does't mean August 13th ( I'll only be 32 weeks). I have a prenatal appointment Thursday and a sono on 30th of this month. So hopefully I get some answers, or is this all normal for someone carrying twins.
