Having problems sleeping

Pynk
Hey all so I'm here typing this at 4am because I can't sleep... Before my pregnancy I would just knock out cold and sleep like a log even though my husband snores like lawnmower... 
Now I would wake up at like 3-4am and can't get back to sleep.. His snores don't help when I'm trying to get back to sleep but  irritate me till I'm jealous and pissed that he can sleep so well I just want to kick him. So I will take my stuff out onto the couch and sleep there...
Is this light sleeping a known pregnant thing? Will I be able to sleep like before? Or is it just gonna get worse....
