Any ideas

Okay so I’m so confused I’ve had my period was normal yea was 4 days late but was normal anyway since coming off had few cramps I’m eating hell a lot more which isn’t normal for me( I’m currently lay in bed starving like I haven’t eaten at all) I’m seriously tired during the day past two days I felt like I haven’t slept but I have my sex drive is up aswell I’m so confused what you all think could be?
