More tired at end of first trimester?

A

I’m 12+4 today so finally nearing the end of the first trimester 🙊 buuuuuut I’m getting WAY more tired than I have ever been! Is this normal? Yesterday I slept for about 9-10 hours, then had a two hour nap on the sofa. Last night I had another 9-10 hours sleep, an hour snooze on the sofa & then I went up to bed & slept for another two hours! I could of probably stayed asleep for the rest of the night but my uniform needs sorting for work tomorrow 😴 please tell me this is normal, if not can someone please help me with something that may give me more energy 😩 I feel so drained!
