birth, depo injection, breastfeeding and periods, what happens?

Ok strange subject but I really didnt know what to write up there that would make sense. I'll start from the beginning, had my son back in Jan 2010 by emergency c-section, had the lochia for 6 weeks ish and then went straight onto the depo injection (before waiting for first true period after lochia), whilst on the injection I was breastfeeding so had no bleeding at all, breastfeed for a year and was on the injection for a year (end Jan 2011), then went on to the Pill till the beginning of June and we decided I shouldnt take the next packet as in 6-7 months time we would like to start TTC, so my question is: How long do you think it will take to get a period/AF? When I came off the Pill before having my son it took 3 months until the first one showed up but then was very regular until I caught 6 month later. At the moment I dont feel like it will appear on the weekend which I think is when its meant to show.. I really can't remember when you count from is it start of AF or at the end of AF for your next cycle, if it was start of I was due on last weekend. Defo wont be pregnant as we are using condoms until December at the earliest.



Any help would be great
