Husband is pissed!

So we do not want any more children and I'm on the IUD. My period has become irregular and sometimes goes 40 days apart. Well is been almost two months without a period. I knew I was 99% sure not pregnant as we pull out too. I told my husband I was getting worried cause it's been almost 2 months since my last period and he blew up and said I need to tell him these things. I should of but I knew I wasn't  cause it's almost impossible! It finally came today. He still won't talk to me haha. Would you inform your husband if you were late even though your period is crazy messed up?
