Hello, I would be happy to help you with your question.
1. On the depo shot you will get very irregular bleeding or no bleeding at all. So it is not suprise that you are getting what you perceive to be a 'delayed' period.
2. A pregnancy
test must be read within minutes - when it is allowed to sit for so long, it is common for it to read faintly positive
3. So, you need to repeat the pregnanct test when you have time to read it according to the packaging recommendations so that what you see is accurate!
