Am i crazy

A week ago i was ready to swear off children for life with how much I’ve been struggling with my first (2 months old)... now i am scrolling through the first trimester group and reminiscing on the whole pregnancy experience, even thinking how it would be to have another soon. Funny thing is i even had a big argument with my husband recently because he wanted to try again soon and i went and got an IUD. Is this just weird hormonal stuff that will pass!?
