SOS I made an uh oh actually a couple of them

Okay my boyfriend lives out of town so this past weekend I went up to see him. We had sex everyday about 4 or 5 times from Friday night to Monday morning. I took a plan B Saturday because I knew he came in me well then he thinks he might’ve Sunday night too. I had forgot my birth control at home so I couldn’t take it when I was our of town therefor when I got home I got back on track but then I missed a pill yesterday so I started my period today. Should I still be concerned about pregnancy? Is this period my actual period or just missing the pill? Help!!
