Sex and delay of period?

I’ve noticed the last two times I’ve had sex it’s delayed my period by 10+ days lol... is that normal?? Or??

I am pretty over weight too (262lbs and 5’5”) and stress a lot from work.

I’m actually 11 days late now of my period lol.. but he used a condom as well as pull out so I know I shouldn’t worry right? But ahh the anxiety lol!!
