I dont know what to think

Me and my boyfriend did stuff the week I was supposedly ovulating but we did not have sex or even go in at all, he did cum but not in me. My period was supposed to come yesterday according to the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> but im not showing any signs of period. I am cramping up but when I wipe after I pee its all clean, theres nothing. Im really hoping I’m not pregnant or anything or that this could just be stress. Its too early to tell because im only 1 day late as the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> predicted for me to get my period. I’ve never missed a period at all in my life so im praying this is just stress related and me overthinking things.
