sleeping and stayingoh awake

okay so I'm 8 weeks pregnant as of lately I'm having a hard time sleeping at night throughout the day and close to like 7 at night I'm tired. I try to sleep but I just can't sleep at night and I end up just tossing and turning or getting on my phone or watching TV. and during the day I wake up around like 9 in the morning and I'm all perky I have high energy and then by the time it's like 12 in the afternoon I am so tired and I can just sleep the whole day away. is this normal during pregnancy.
