Baby 4

So I have since having March baby been dead set again having another baby. My husband expressed after baby was born he felt like we should have one more. I told him no and he left it at that. Since then I’ve told everyone I know, whether they asked or it just came up that our March baby was our last baby. The last month, my mind has been changing. Now if we like we should have another baby, I know my husband is on board if I want to but I feel super stupid cause I told everyone we were done. My kids are 4, 2 and 7.5 m. I would want to get pregnant in the next 2 years, maybe as early as March or April. Has anyone else been where I am? I know ultimately it doesn’t matter to anyone but my husband and I but where I am from everyone had 2 baby so even 3 was pushing the norm.
