Curious

So I talked my boyfriend into having sex with me without a condom, & he cam in me (6:30pm) and we went to go get a plan be (9:00) we got it  kyst imcase we wanted to use it we went to eat, then went home I never took the pill til (1:30-2:00am) so I'm wondering is it possible to get pregnant ,that quick, before I took the pill, and if so will it hurt if I took the pill after the semen reached the egg ?
