When you start having sex again, can it throw your cycle off? ( I.e., period is late a couple days?..

So I started having sex again, and it’s been pretty great. We always use condoms, and he never finishes in me.

I’m supposed to get my period in 4 days, but I usually experience certain period that tip me off when I’m getting my period ( sore boobs, lower back pain, bloating..) . I’ve had some breast pain and little lower back pain, but not as much as I usually feel before my period starts.

Well, I’ve been stressing and overthinking that I won’t be getting my period anytime soon due to being sexually active again, and my stomach has been off the last 5 days (using the bathroom too much), due to being so stressed out. (I think)..

My question is: is becoming sexually active again (plus stress), can throw your cycle off a bit? As in delayed period?..
