So, What do I do?? Had been trying to have a baby, when one day I started spotting.?

I didn't bleed much and don't really think it was my period, but since that day I have been bleeding for 30 days out of 34. I skipped a few days here and there. With no blood at all...crazy.. What do I do? I would contact my doc., but they will say more than likely is that its all normal.. That about all I ever here. I just don't know what to do...Now, don't get me wrong, they haven't told me that I was normal for bleeding 30 days, just afraid that they would tell me that. Had things before that just didn't seem normal and they said it was. I feel real tired and starting to think I look pale. Please help! What do I need to do?
