Would you be upset if husband forgot your anniversary?

So yesterday was our two year anniversary. And I knew what day it was but I didn’t say anything because I was waiting to see if he remembered and sure enough it was almost 11 at night and. Nothing was said so before I went up stairs I went in the kitchen I wrote a note that said oh yeah happy anniversary 🙁 he came up didn’t say anything went down to get a snack and when he came up he was like it wasn’t today it’s tomorrow and I said no and by that time I’m in tears (nine months pregnant due any day) was I right to be upset or is it just a date and should get over it. Haven’t talked about it since and he said he was sorry 😐
