4 days late? Negative test?

Alyssa

I am currently going on 4 days late. I tested the day on my period (-) and I tested this morning and it appeared to negative (pretty sure I was seeing what I wanted to see vvvv faint line within the 5 mins). My cycles are very normal and I usually get my period on 27-28 but never late. The only things I have felt are fuller and slightly sensitive boobs, lots of bloating/pressure feeling in pelvic area and cramps here and there. I thought for sure I felt my period was coming this month but nothing!! I just wanted to know if it’s usual to wait so long for a positive or should I be concerned?
