I Missed My Period Last Month, (I Spotted For A

I Missed my period last month, (I spotted for a few days and that was it) then I started the beginning of this month, very light, then had a bladder infection. (All the while still bleeding somewhat lightly). Went to the doctor on the 19th(thurs) to have tests done since the bkeeding went down but didn't stop so they ran a few tests along with a pap. On Tuesday the 24th I started bleeding VERY heavily and clotty. to the point where I am changing my pad sometimes 6-7 times a day. is this normal? It is now the 27th
