When does the sleeping end😩😩😩😩😩😩

Im 12 weeks pregnant and i feel like alllllll ive done is sleep!!! When does this end! Its sooo difficult for me to wake up in the mornings, like i just cannot shake my sleepiness, and then i still need a nap throughout the day!  I was so active and on top of everything before i got pregnant now im lucky to make enough time during the day for work , school and eating haha, someone please tell me i sort of go back to normal soon?
