I just recently got the depo shoy 2 weeks after my period and I has unprotected sex 4 days after now I'm 4 days late for my period and I'm having morning sickness and have frequent urinating I'm naseous all day extremely tired bloating and I'm dizzy I have some times where I'm hot and I'm sometimes out of breath oh I forgot to mention that 5 days before my period I had brown watery spotting then I missed my period currently 4 days late so am I pregnant on the depo shot?

No method of birth control, including sterilization, is 100% effective.

Yes, you could get pregnant while "on the depo shot."

The only way to know is to test.

And can I just add that the depo completely stopped my periods for the 4 years I was on it, when I just started getting it I experienced side effects such as sore breasts and food cravings,
