loosing virginity? condom with pull out mehod? (BOTH AT SAME TIME)

i think im going to lose my virginity this weekend. i will be out of my fertile window and my period should begin a week after. he isn’t a virgin and used the pull out method WITH condoms before too and he assured me he’d protect me and make sure it’s okay. but i’m still worried i will be pregnant. what are the chances? are they high? has anyone gotten pregnant from the pull out method WITH a condom? i’m so stressed, i do love him dearly. i wish my anxiety didn’t make me worry so much about these things...
