Can I get pregnant if I don’t get my period?

hi, so I have a question. I’m planning on having sex soon and I just want to make sure I’m being 100% safe. I have the nexplanon implant in my arm and that has stopped my period from coming. I was just wondering since I dont get my period does that mean there is no chance for pregnancy? I’m planning on using a condom to just to be safe because I know that nothing is 100%. However, I was just curious?
