Advice or suggestions.

I have been feeling off lately!! I’ve been overly tired. Like constantly need to sleep or I get a severe headache! I just have zero energy to do anything anymore. I am not pregnant as I took a test today to rule that out. But I am taking the birth control pill Larin. This has just came on so sudden I’m not sure where or what is causing me to feel this way. Please any advice or suggestions are appreciated.
