Missed period

Let me give you a little background information, I stopped taking my birth control when I was finished with my pack I December. I know it's normal to be off on my cycle since my body is adjusting to not having the birth control, but I've had my period January & February at seemingly normal times. So far according to glow I am 2 weeks late.! I've taken 3 tests at different times & all came back negative, but still no period. What's going on?! Should I see my gyno?!
