4mths pp and pregnant!!

Took 2 tests within 2 days and waiting for my blood test to come back. I am in shock and haven't even begun to think how I'm going to tell my husband. We already have two. And agreed no more. Was waiting on second period to get the iud but that didn't happen. How would you ladies process this/has this happened to anyone else and how would you tell your husband?

Please only positive comments and nothing negative or judgmental
