Plan B and bleeding/ pregnancy ?

Lu

So i took plan B on the 17th may. On the 18th and 19th i had unprotected sex.

Today (22d- 5 day after taking plan B) i have bright red bleeding. My nipples are super sore and i felt nauseaus and exhaudted this week.

So even though i have this bleeding, because i had sex AFTER the plan B too, can i still be pregnant despite the bleeding ?

Also i had sex in my fertile time
