Plan b symptoms

I took plan b 8 days ago and I experienced symptoms right away like spotting and cramping. That went away by the next day but after that my breasts have been swollen and tender. Just a few days ago they stopped being tender but are still swollen. I’ve also been moody for 5 days now and fatigued. I looked up online how long symptoms last and websites are saying 3 days at most. But on this app so many women have symptoms up to a few weeks after taking it. Ive been on birth control pills for 5 years but I’m pretty sure I still have symptoms a week later. How long did your symptoms last?
