Help !!Sex without a condom on the pill?

So I've been on the pill for just under two months now and last night me and my boyfriend had sex without a condom,I am very persistent in taking my pill I take it at the same time every day,I made sure my boyfriend didn't cum inside me so he pulled out,but I've been reading a lot on <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> and may people are saying it doesn't fully work until 3 months? Should I go and get the morning after pill or should I be fine? Also I know I made him pull out but you never know with pre cum etc
