Late by 8 days, taken waaay too many pregnancy tests, all negative. Ellaone two cycles ago?

I took Ellaone in December after a condom broke during sex. I got my period shortly after but it lasted FOREVER (December 8th-20th according to my <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> app which I would’ve logged myself)…

Now this period is 8 days late. I’ve taken like dozens of pregnancy tests - all negative. (I also have a child and have been pregnant before, and don’t feel pregnant at all, I remember nausea was a dead giveaway for me with pregnancy)

Has anyone had plan b or Ella mess up their cycle completely? I have taken plan b before and Ella and don’t recall it messing up my cycle horribly but I do recall it causing insane mood swings.
