Implantation bleeding or..?

Aaliyah

Hey everyone. I need a little help. I’m wondering if this looks like implantation bleeding to anyone or if it could be something else. My period is due in 12 days and I took a plan b about a week ago or so. I did the deed twice the beginning of this month but I’m starting to doubt the plan b worked because I’m having early pregnancy symptoms such as tender breasts, mild nausea, frequent peeing, irritability, etc but could those be plan b side affects? I’ll include some pictures.
