When I sleep on my left side-my right side falls asleep (tingly feeling)? I do have lower blood pressure?

I have noticed this for a few years - I am now 30 years old. Before I had my first child (now 2 yrs old), now I am 8 weeks pregnant & it is happening moreso. Has anyone experienced this? For instance my last blood pressure was 104/54 just yesterday. I plan to mention this to my ob/gyn at my next visit (in March) but until then does anyone have any suggestions - besides the obvious of only sleeping on my right side?When I sleep on my left side-my right side falls asleep (tingly feeling)? I do have lower blood pressure?
Well impossible for me to get pregnant. But it might be because of the added weight to your left side. Do you sleep with your hand under your pillow or any way that makes your arm put pressure on your heart? I dunno When i sleep on my left side my heart pumps extremely strong and i can feel it so i cannot lay on that side ever. When i do some times i will wake up and my arms will be asllep both of them i figured its cause im putting pressure on my heart and cutting off blood flow somewhere. best just to avoid laying on that side. :S
Put more blankets on your bed or sleep in warmer pj's. I live in a very cold environment and when I don't have enough blankets on my bed whatever side was up is usually asleep. My doc told me that it was because I get so cold at night. You might also want to try sleeping on your back because the extra pressure of your baby might be just cutting off enough of your blood circulation that your right side could just be falling asleep.
