Possibility of being pregnant? Please help

So my boyfriend and I last had sex on June 18th. He used a condom. My period was supposed to start on the 6th of July but it is now July 10th and I still haven’t gotten it. I took a pregnancy test on the 8th but it was negative. I’ve been trying to remember if there was any way that anything could’ve gotten inside me, but I’ve been so anxious that I can’t remember anything and I’m just overthinking it. I don’t think the condom broke, but we never checked because before he came he pulled out, took it off, and jerked off after to finish. I’m just concerned because my period has never been this late and we had sex 5 days before my expected ovulation. Should I take another pregnancy test? I’ve been so worried about this.
