Sooo... I was supposed to get an iud today and they tested me and I’m pregnant again!!

We wanted more kids but not this close together. My husband doesn’t handle the infant stages well so he’s beyond overwhelmed. When I told him he thought I was joking. Then I showed him the pic of the test and he said “looks negative to me”. Then I explained that it’s definitely positive and he just said "no" and went upstairs. This is insane
