Sleeping too much 😴

I do really sleep for 16 hours straight and still it’s not enough for me, I still do feel extremely sleepy and exhausted the rest of the day and too lazy to do anything, even naps never helped... am 19 ... my period is within 5 days .. this happens only during ovulation and lasts till my period ends like 15-17 days each month , is this normal in general ??!

Thank u so much 🙏🏻
