How long to wait until I seek help to bring on AF so I can at least chart?!?! Or is that even possible? Was on Depo for 9 years. I don't get AF while on Depo so have no idea of my cycle times. Only off depo for 15 days now, but any other time I would "miss" my window for my next shot I would start AF within 2-4 days. Now that I have purposely stopped no AF in site for 15 days??
