Are Headaches And Abdominal Bloating Symptoms Of Pregnancy?

Hello, well my period is usually on time & I m only 8 days away from starting my period again but recently I ve been having horrible headaches, bloating like crazy, my breast are pretty sensitive & for 2 days now when I wipe it s light pink/clear discharge. Could I be pregnant or should I just wait to see if it s because of my period? I have a test at home just not sure if I should take it. I also have a swollen spot where my right ovary would be that hurts like crazy & it does worry me. Just not sure what to do at this very minute. Thank you (:
