I'm going crazy

I have no patients lol..

I have been getting light pink color on t.p. after going to the bathroom. I don't get periods without taking provera so I'm a little confused. Is my body trying or could I have possibly ovulated and maybe implantation bleeding.. But can implantation bleeding last a whole week off and on? Our bodies are so confusing. I go and see a obgyn tomorrow but my mind is racing with different possibilities
