Period on and off for over 6 weeks **TMI**

This doesn't have much to do with my up coming WLS but here's the deal:

I take Provera and back in March my nephew got a hold of them and ruined 6 of the 10 pills. I had already taken the other 4 and was thinking to get it filled again but never got around to it and I assumed I probable wouldn't get it this time because I didn't take all of the pills. Well about 2 weeks later I got my period for nine days! And it was VERYheavy ( I actually considered trying Depends to see if I could get relief from the dubeling up on protection) Well it ended the on a Saturday then the 8 days later (Easter Sunday) I started again. I thought it may have been spotting but it continued on just about as heavy as the last week and lasted again till the next Saturday. Then I was off for 6 days and started again the fallowing Sunday That was last week and it wasn't nearly as bad as the other weeks. It ended on Saturday and I've been clear all week but I'm worried it will start again on Sunday or something. What could be going on will me? Do I need to take another month of the Provera to get back on track??? Am I going to need a hysterectomy???(my sister in Law put that one in my head)

I know its kinda confusing, But any ideas are appreciated!! Thanks!

trust me once you have the surgery your periods will straighten out very quickly.
also don't worry about having your period when you go into surgery, they deal with these things all the time and most women usually have a period right after surgery because of the medications they give us.
my periods were very screwed up before my rny--but for the last almost 3 years they are like clockwork.

hang in there it will be better very soon!
