Condoms

So I had sex with a condom the other day. I just recently got the arm implant and I had had it for more than seven days before we had sex but I’m just not sure how effective it is yet. My boyfriend wore a condom the whole time and pulled out with the condom on before finishing. I checked the condom with water afterwards and no water leaked out of it. Even if my new birth control isn’t completely effective yet, am I still okay?
