Ladies I need some advice

Okay so my period is two days late . Me and my spouse aren’t ttc so we use the pull out method right now ..... he is so scared that I might be preggo .... ( we had a big miscarriage 2 years ago this month and it hurt him forever) he is texting me saying he has so much anxiety right now ..... how do I help calm his nerves! I keep telling him that sometimes your period is just late but he really is going crazy
