Pregnancy and bc?

So i started my birth control pill(combined) on 17th of February,on the first day of my period.I had sex without a condom 10 days after,just in case.I am extremely paranoid and i take my pill exactly at 9 am in the morning every single day.Today was my first ,,break day” where I don’t take the pill for the next 7 days and my period is supposed to come.I am kinda scared because my period is still not here, even though i read that many women get their period on 2-3 day.I have sex without a condom and my bf never cums in me.Could i be pregnant,i am going to test in a couple of days.
