canceling wedding due to cramps

A.Y.L • Hello! Names Mrs Lopez my husband and I are trying to conceive our rainbow baby 🌈👶🏽 a sibling for our fur baby! 🐶
Well this thankfully didn't happen to me but I was just wondering if anyone had this happen to them? My cousins wedding was last weekend I was one of her bridesmaids and I didn't show up because I was in pain from menstral cramps and other fun stuff. But I was just wondering what if it had been her??? Would the wedding happen?? Has this happened to anyone?
