Sacred to test

Kathryn • Hello everyone, my name is Kathryn and my fiancé and I are trying for baby number 2. We have a 4 year old daughter
So scared to test! AF is due today but has not started yet but it has known to show up in the evening. I'm not feeling any cramps or anything but sometimes not often sometimes that has happen. I'm scared to test cause if I test then start or see a negative.
