Can someone help me??

So I am 10 weeks PP. no period yet. I had sex 08/07 or 08/08 I can’t remember the exact date. He finished in me & I was supposed to take a plan b. But I’m on depo so I wasn’t really worried. But now my period hasn’t came no sign of it at all & I am not breastfeeding. Should I take a test?😩🙄
