Trouble sleeping

So I think I’m around 7ish weeks , I am not sleeping or I feel like I’m half asleep where I’m not moving and my eyes are closed but I can still kinda hear what’s around me?? I feel like that’s my “ sleep “ for most of the night. Any advice? I really don’t like taking things like Benadryl because for me it always rolls over into the next day I feel worse during the day. I was taking L-theanine mixed with magnesium before I got pregnant and that helped but now I can’t take L-theanine anymore.
