My depo expired 2 weeks ago then we have intercourse .can I be pregnant?or it is safe

Yes, you could be pregnant, assuming it was unprotected sex.
BUT the effects of the shot can take upwards of two years to dissipate.

Yes you can be pregnant.
Sure, there may be lingering probabilities, but it doesn't help if it's say 50/50 for another 2 weeks and you fall into the 50% that gets 100% pregnant.
