Plan B bleeding like period 🤔

I finished my period on July 14, and on July 16 I had sex using a condom with my bf but we wanted to try for the first without it so he cleaned himself and only stroke it one try very quick for like a second. For just in case and peace of mind I took a plan b (Her Style) for the first time the next day in less than 24 hours. Five days later (July 22) I supposed to be ovulating, but I started bleeding like if I was on my period having heavy flow, cramps, diarrhea and even tender breasts. Now it’s been four days and I’m still having these symptoms and I want to know if this is an early period because of plan b or spotting before period and if my period would come late because I supposed to have my period on August 7. I know the pamphlet says I can have similar symptoms to periods after taking it or get early period, but want to know since it’s my first time taking one. Thanks in advance for the help.
