I have also been on the Depo contraceptive injection and had my last injection June 2006. My periods have not yet returned, but did have some 'spotting' in Jan and Feb but this was hardly anything at all. I was told by my Practise Nurse that it could take 18 months for my periods to return, but am getting impatient now waiting. I was on Depo for 3 years (maximum recommended for is 2 due to the fact it can increase the chance of Oestoporosis). September 2007 will have been 12 months since my contraceptive 'ran out' so I would say to anybody wanting to conceive is, after this time, maybe contact your GP/Practice Nurse just to rule out any problems which may arise.
