Induce a period

Has anyone induced a period before?  How did you do it?  I've heard of using Vitamin C, Dong Quai, parsley tea, hot baths, sex, etc...but I question safety/legitimacy of some of these methods.  Anyone successfully (and safely) induce a period?  Any side effects to your method?  
After my 2nd pregnancy loss, my period just won't start and I'm so frustrated and sad.  It has been over 6 weeks now and I can't take it any more!  I know I'm not pregnant (DH and I have been using protection since the loss as my OB instructed us to avoid pregnancy for at least a couple of cycles, but I tested anyway just to be sure - BFN).
