Question about plan b

Anna

Hi, so I’m on birth control pills and today I was supposed to start the “period” pills but I skipped them bc I didn’t want a period bc my bday is in two days. So tonight I started a new pack. My boyfriend and I had sex and I’m pretty sure he came inside me a little before pulling out. Then, (tmi) when I got home I masturbated and orgasmed. Do you think I should get plan b?
