Delayed period?

lex ♡ • Lex, suck it up buttercup 🦄
I had sex for the first time a couple of weeks ago  and almost every week since the first time. we use protection every time  and he even pulls out, and I'm supposed to be coming on my period today(the 29th) but I haven't started it yet. My last period was June 1st. I'm not too worried but I wanted to know is it possible that sex could delay your period.
