It's unlikely if you were one day late.
According to their website:
Depo Provera is cleared from a woman's body about 6 to 8 months after her last injection. After discontinuing Depo Provera, women may also have a 6 to 12 month delay in return of fertility.
you have 7 days to get it after your 'due date'
for example, if you were scheduled to get it on the 1st, you can get it up to the 7th.Can I still get pregnant if I'm on Depo Provera?
The odds are in your favor because even though the shot ran out, sometime you will still be infertile for up to a year after it runs out! I was on it for 2 1/2 years and liked it a lot!Is your vagina tighter when you are pregnant?
