so tired 😴

Hi ladies my husband and I are currently ttc our second child. I am only about 5-6 dpo I think. Lmp was 10/16. With normal cycles. I am extremely tired for the past couple days with no change in my daily routine. With my first child I slept my whole first trimester away but we weren't tracking we were just trying without really paying attention to when we needed to BD. So Idk if I actually felt these symptoms early on.... my question is is it to early to feel tired? I definitely feel like it's to early to test but just weird Bc all I want to do is sleep....
