Suggest Treatment For Heavy Vaginal Bleeding And Stomach Pain

I have always had regular period for about 17 years now, never came on early never came on late, nevr had cramps or any pains while I was menstrating. Well about 2 months ago i didnt start like i noramally do i was only spotting, I figured it was do to my diet change or stress that I have been going through lately. (there is No chance in pregnancy!)So finally about a month ago I started bleeding again and I started using the birth control lybrel so that I can be free of periods. I took directions as followed, I started my first pill the day I started bleeding. Bleed lightly for about 2 days then started spotting again, I assumed that I was not starting my full period but I continued with the pills as directed. Now for the past 9 days I have been bleeding extremely heaving, using pads about every 2 hours and huge blod clots, while I urinate and while I wipe, not everytime but it is a lot. Im also haveig really bad uterus pains and stomach aches more so towards my left side, I actually feel pain running down my whole left side of my boby at times, it feels like a lot of pressure is at my uterus, I'm tasking ibuprofen every 4-5 hours to calm down the pain. Also about a week ago I went to the denist and turns out I had an infection in my mouth and he perscribed me clindamycin, which I'm completely done with the antibiotics as of 2 days ago but I was wondering if that has any effect on my extreme bleeding or not? I would really like some advice as to what to do because at this point I can not get into a doctor for a couple of weeks, this surely can not be normaly I just really need some advice....please help
