Sleeping too much?


Im 19, good health, I’m currently 26w1d and I sleep at least 10-12 hours a night. I eat breakfast in the morning and then it’s like I’m tired again and I could nap for another 2 hours. Wake up for lunch then I could sleep again... is this bad? Is this too much sleep? This is my first baby, it’s a boy. I don’t know what to think about my body being as tired as it is. I know I was very fatigued in the first trimester but shouldn’t it be gone by now? I stay at home and I don’t work so my schedule is completely up to me which makes fighting sleep harder. Someone please give me some advice!
