Period every morning for a month

I get my period every morning. The minute I wake up it starts and it finishes around 11. Its always a lot of blood or clotted. If I don't get it in the morning it will come later in the arvo for a few hours. I'm on the pill and not the white tablets yet. I feel dizy and tired all the time and nauseous. Could I be pregnant?! I felt like this a few years back so I went off the pill cause I was experiencing the worst cramping. My ex refused to wear a condom so I went back on it and was already pregnant. Now I'm feeling the same way again.
Is there something wrong with me or do you think I could be allergic to the pill?
