Can someone please help clear my concious!

Okay so, i Take Orsythia birth control every single day.  But i don't always take it at the same time every single day.. There's maybe a 2-5 hr difference.  But after this past period i just had i've been taking it at the same time each day. So on the fourth day or so out of my period and taking my birth control at the same time, i had my boyfriend cum inside me for the first time.  I am still taking my BC at the same time for extra saftey but my question is, do i have a likely chance of getting pregnant now and should i go take a Plan B..
