PLAN B PILL questions help!!

Hey ladies, so I had sex a few weeks before my period and took a plan b one step. And then also had sex on the last day of my period. however the next morning I took ANOTHER Plan b anyways. and just 3 days later I got another period for 7 days. My <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says I ovulated 2 days after I ended the SURPRISE cycle. I also had unprotected sex with my partner that night too. I chose not to take a plan b again because of the way my body reacted by giving me an extra period. My question is... would the plan b work and maybe I didn’t ovulate like glow says? I’m supposed to start AF in 4 days is what glow says. So I haven’t tested yet. But, I’m freaking out a little. Please help? What should I do? Should I just call my doctor? This was my first time ever taking them.
