How to get rid of constant pregnancy exhaustion?

So I'm only 6 weeks pregnant but I feel like I am constantly exhausted! Since becoming pregnant I haven't gotten a full night of sleep! I don't know if it's the hormones or the anticipation that a baby is comeing!!Iv completely cut out caffeine like coffee and soda since caffeine is bad for the baby's development and that's making me tired as well! No matter what I do I can't seem to get motivated to do anything even my apartment is a mess because I'm too tired to even clean! Ladies, is there anything I can do to get some energy back! I need to get out of bed!!! 😴
