No period wth??

Gi

I usually get my period on the 14th. But I took a plan b in March on the 4th. I didn’t even need to take it but I freaked out & took it anyways. Then I got my period March 15th until the 20th. I had spotting at the end & beginning of April. For about a week but my gyno said it was from the plan b.

Alright now to two weeks later. I was expecting my period either the 14th or 15th. But I have been stressed, my daughter caught a stomach bug again within 3 months of each other & I have emetophobia, so I was in panic mode & having terrible anxiety. Idk if stress is causing it to be late or the plan b is still messing with me. But I have been using protection. But I will still test anyways in 5 days after, if I don’t get a period. Now on my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> it says my period is due tomorrow randomly? Not sure why but it said the same last night when I checked it. Perhaps a period change or stress?
