I have a question about something that is driving me kind of crazy. 9 months ago I got one shot of the Depo. On the 13th of last month, August 13th I had my first period. It lasted until around the 20th. I then spotted for a few days beginning on the 24th of August. Today is September 27th and I have not seen a period of any sort, not even any spotting. I have taken a few pregnancy tests and each was negative. Is it too early to test or should I just expect a period by the beginning of next month?
