4 days late on period ... Pregnant?

I have a 4year old daughter before I was pregnant with her ... I didnt track my periods and then it was irregular. So I found out with alot of morning sickness , I was experincing ...... I had a miscarriage in late May of this year and I have been tracking my cycles  faithfully. My partner and I want another child but we were thinking not until next year lol well if pregnancy comes soon , then we will still be excited :) I have never tracked my cycles and be off by 4-5 days late .... I mighy be pregnant , you thinl?
