No sleep for weeks

It’s been 2 weeks now and I’ve maybe had a few hours of sleep altogether. No matter what I do I can not sleep. I’m 17 weeks. I’m not uncomfortable as I do not get a bump with pregnancy. Unisom does not work, benedryl does not work, and I’ve been messaging my OB for more ideas as these are the ones she gave me. Is there anything else I can do? Benedryl will get me tired but then I just lay here… all night.
