I switched to the pill depo 3 months ago last month I started spotting for a week cause I guess my body got rid of all the depo toxins... well this month I have 2 days left and haven't had any period or any sign of my period... but on day 2 I went to take my pill and dropped it and couldn't find it for anything so I took the next days instead and just kept going so I started my red pills a day sooner... could this of thrown off my body enough to not have a period this month or could I be from the 3 years of the depo shot?
