Is this normal

Tiffany

So I don't have my period for another 20 days but I'm getting sick and so extremely tired it's not even funny like I want to sleep all day and having an extreme pain in my lower abdominal area and massive headaches.... And my ovulation week starts tomorrow though. I really want to sleep all day and I barely eat anything lately. Me getting sick woke me up out of my sleep and now I'm grumpy cuz idk if I'll be able to go back to sleep now. I don't know if this is normal before you ovulate or it's something else
