All of My Information:

I am 22, I am very sexually active and have HPV (I have had it for several years now) I get regular pap smears and my most recent one was in April and came back normal. I recently had Chlamydia (about 3 months ago) and took antibiotics. I haven't gotten checked for anything recently.

About 2 weeks ago I started my period. I am on Yaz and have been on it for about 4 or 5 months now. I take is pretty regularly. My period started normally until I started to take Excedrin more prevalently because I have to get a root canal on a tooth and I can't handle the pain of my tooth. Last week I was taking about 6 to 8 pills a day. My period got much worse. I have been cramping a little more and I have have been bleeding dark, heavy blood with chunks of something in it for about 3 days now. I stopped taking Excedrin for the past couple of days. I need some honest answers. Please tell me what should I expect just so that when I finally do go to my Gyno I don't break down right there. Thanks.
