Is my bf reacting normal... its stressing me out even more😭

I'm supposed to get my period in 4 days but we were very stupid and idiotic and didnt use protection like morons and now there's a pretty big chance of pregnancy.. like really big. So basically now the only thing we are relying on is whether or not I was actually ovulating or not... ever since then he has been SUPER distant with me. And every time we talk he is always asking me if my body feels okay or if my tummy is cramping and stuff... but its stressing me out even more that he's being distant. I know he is super stressed over the situation but why is he being so distant with me now😔😔😔
