Natural Remedies for fatigue 😴😴

I missed my period for February, I took two tests both came back negative and I took one last week and the week before that. According to glow nurture I would of been 2 weeks pregnant when I took the first and 3 weeks with the second now wonder why I didn't get a BFP😔. I'm guna wait a few weeks before I take another test I'm pretty positive I am my body just feels really different, I would now be 5 weeks today , but in the meantime I feel extremely exhausted like I'm not even sleeping ( but I am), Any home remedies recommendations to help with fatigue ? I have tried to take naps I wake up really tired !
