Paranoid

Has anyone had the stress/anxiety of being pregnant delay their period? I have been getting really bad anxiety about the possibility of being pregnant, and now my period is one day late which i know is normally not supposed to cause worry but for me it is because i have already been paranoid about it. The worst part is that everything has been normal, and i’m also using Paraguard which is 99.4% effective and me and my partner use withdrawal as well. I’m just wondering if it is normal for that type of stress to delay a period, and what you guys might do to calm that stress down? Thanks!
