SIL overreacting big time.

so, i got pregnant, and my due date is on the exact day as my sister in laws wedding day, well no it was not planned but she’s furious with me! she literally will not speak to me, cut me out of the wedding and told me that this child and I ruined her life?? all because of my due date?? i feel bad but its not like i can change it or anything.

Its also my first child, and my doctor said only 5% of women go on their due date, i explained this to my SIL and she just is still being the rudest human being over it!!!
