Pill and Withdrawl Combo

Megan • In love with my boyfriend and very pro choice :)
I have been on the Seasonale (3 month pill) for 5 months and haven't recently started not using a condom with my boyfriend. He still pulls out and does not ejaculate near me at all he has perfect timing usually pulls out like 5-10 seconds before he finishes. Is this an effective combination against pregnancy?
