Please Help Me!!

I'm 16. I just had sex with my boyfriend late night with a condom. I am in birth control but it's a cheap brand, I take it on time most days but sometimes I fall short every once in a while, sometimes about an hour later. The past week I made sure to take it on time every day. My boyfriend came inside me in the condom when I asked him not to but we pulled out halfway. I'm very paranoid about sex, so I asked him to do the test where you squeeze it to see if there is any leakage, but it's always hard to tell. I am paranoid that it could have broken or maybe my birth control is ineffective (Tri-Nessa is the brand), I'm supposed to start my period today or tomorrow. Should I go get a morning after pill?
