I’m so mad!

I’m so madddd.. I was telling my husband that I’m 6 days late on my period. And he laughed and said “you’re always late”. And I’m like yeah a day or two. I don’t know why he’s taking it as a joke .. or he’s nervous that I could be pregnant but I’m just very upset. Like why even laugh about it ? Ugh, I’m probably overreacting though. I don’t know but that hurt my feelings.
