I have to say, yes unfortunately it is a part of pregnancy. I woke the same hours as you for just about the whole of my pg with ds. However, i don't want to scare you, but unfortunately it has not gone away for me My ds is almost 2 years old, I have been suffering insomnia since falling pg with him and it hasn't gotten any better. I think after your pg you should continue with the accupuncture because it obviously works well for you. Hope I haven't scared you, sorry.. but just wanted u to know that it can get worse.
