had sex when period was late, someone please help for advice!!

Yesterday I had sex with my boyfriend and we hadn't done it for a while so he cummed quicker than expected!! We didn't use any contraception, it was standing up doggy and he pulled out and I turned around and he was cumming, but I know about pre cum and things. However at the time I was already 6 days late on my period and I'm honestly so regular with my periods, I still haven't got it and I would usually get symptoms three days or so before and nothing,. I'm really worried so could anyone give me advice please!!💜
