I'm confused!

I think I'm pregnant, me and my husband have been trying for one year and 4 months. Since my miscarriage... I'm 4 days late on one period app and 6 days on another and I'm never this late my periods are very irregular but I'm never been this late before, my boobs are also very sore, crazy back pain, and I'm more tired than usual! I'm gonna take a pregnancy test tomorrow but I would love opinions what people think. I really want to be but I'm so scared to test because I don't want to be devastated.
