My Ladies on the Patch

I have been on and off of the patch for a few years now. Recently I was off of it for a 2-3 week period while waiting for my doctor to refill my prescription so long story short I had sex without a condom during this period and wondering just how likely I am to get or be pregnant. He did bust his business inside of me about 2 weeks ago. I haven't had a period but I recently restarted my birth control this week...not sure if I should visit the doctor take a test first or if it's too soon to do anything. Advice???
