only had a sex a few times and nervous

so i’m on birth control, I don’t take my placebo pills at the end of the pack though. I haven’t had sex in probably a year and me and new boyfriend had sex a few nights ago. we started with a condom but it slipped off so we put it back on and kept going. i’m worried some precum might have been on the outside of the condom when he picked it back up. He pulled out when he came ( just for safety) but i’m still so nervous about precum. I haven’t had sex in awhile so getting back into it has me so nervous!!!!! I just got off my period last week.
