Finding myself having to take nap once a day now is that normal?

I'm 25 weeks will be 26 on Saturday. Lately for a week now I have to take an hour for atleast an hour and a half to feel rejuvenated . I wake up at 8am by 12pm-1pm I need a nap till 2-3pm and I'm fine for the rest of the day. I know this is towards the end of my second trimester so is thar why? My sleep at night isn't the best either.
