Sleeping nonstop

Hello I’m currently 8.5 weeks and I’ve been sleeping a lot these days. I sleep for about 7-9hours during the night, and an additional 2-4 hours (sometimes 1 nap, sometimes 2 naps) during the day. This has been going on for about 2 weeks now. Is there anything to worry about sleeping too much? I just feel so so so tired all the time so I allow myself to sleep anytime fatigue hits. I know fatigue is part of early pregnancy, but does anyone else sleep 10-13 hours a day in total..?? I’m worried as it feels too much
