Suggest Remedy For Heavy Blood Flow After Having Ipill

I took an ipill on 17th july around 48 hrs after sex just for precaution because my boyfriend wore the condom upside down and then corrected it. I had slight pain and blood drop with slight white discharge every now and then. After i had sex today, by the evening i started getting cramps and i started to bleed but now the bleeding is of very heavy flow and had to change the super flow tampon almost after half hour, please help?
