Ovulating on the pill?!

Hi everyone,
I started my pill pack one day late this month on accident; I switched <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">period apps</a> and confused my days. I was supposed to start the pill on Friday the 28th but instead started it on Saturday. I took two pills that day to get back on track. 
Because I have obsessive compulsive disorder I tend to need reassurance and feel the need to check everything. So I bought an digital ovulation kit and got a smiley face, which means I'm at "peak fertility."
I'm confused, is it possible that I have ovulated because I started the pill late? 
Thanks in advance.
