Period..ella plan B..hormonal disorder??

So i took plan B Ella 25 february, my period was on and Off, it came 1 week later , (i took 2 pregnancy tests after 21 days after the intercourse and they were negative..)

and then the Next time it came after 2 weeks and 6 days. I always experienced period symptoms and now i experienced them for 5 days, Sore breasts being the biggest one, and now my breasts started getting almost back to normal(They aren’t that painful anymore)... but no period.

It’s driving me crazy. (My period usually comes after 3 weeks and 4 days) now 3 weeks and 4 days passed and eve told me that today i should be getting it.

Is it because of the hormones in that pill? It makes me anxious Even though i don’t know why.. pregnancy is excluded but i want my period back to normal😂 when will the hormones wash Off? Did anyone else took Ella Plan B??
