Trouble sleeping?

Sarah • I have a 9 year old and a 6 year old. My husband and I conceived after trying 10 months. Due February 2017.
I'll be 14 weeks Friday. I have been having so much trouble sleeping. Getting comfortable, staying asleep or bothered by these non stop dreams. Anyone doing anything to help with these issues? Last night I slept from 7 to 10 pm. Was up from 10 pm to 2 am... back asleep from 2 to 6 am. Today in feeling awful and it's making my nausea so much worse... Any advice is much appreciated!!!
