Insomnia! Help!

So I've been trying to go to bed at reasonable time. Well once I get there I can't sleep i keep tossing and turning. I don't want to wake up my husband because he works full time so I try and stay still. I just stay up till like 4:30 am and wake up around 12 but now I'm fixing to start my job. I can't have this sleep scedual what do I do also I might be pregnant will find out Friday. So I don't want to take any medication that would hurt the baby.
