5w and CRAZY insomnia!

Jas • 2017 will be a better year! Working to make my hubby and son proud! #72915
So I've always had problems sleeping, but just in this week since getting my BFP I've barely slept at all! I don't know if it's anxiety jitters or my life-long sleep trouble kicking back in full force. Doc told me the Ambien I was taking was category C, and it should be used in absolute moderation or not at all. But that was the only med that helped me actually sleep! What can I take as an alternative?
