Am I pregnant?

Victoria • Just a bisexual girl with Jamaican roots🇯🇲💕💜💙

So, I've been on the pill for 4 weeks and I'm supposed to be on my period three days ago. Before my period, my boyfriend and I had unprotected sex and had withdrawn (pull out method). Instead, I've been having UTI for 4 days and not started my period. What do y'all think? Should I go see a doctor? Is it normal? Am I pregnant? I'm very frightened now. Please help me!!!!
