Sleeping on back while pregnant!

How dangerous is it? I can't ever seem to get comfortable sleeping on my left side. If I sleep on my right side I end up on my back which is most comfortable for me..not sure why because before I was pregnant I always slept on either side. (I'm 25 weeks btw). I just feel bad that I'm not sleeping on my left side all the time!
