Two days late

Hi all! Just searching to see if anyone has been in the same position as me! On September 11th I had my mirena removed, I was on it for about a year and a half and I was at the end of my AF also. So my fertile days were the 21-26 I had sex since my mirena was removed and everyday on my fertile days! I've never had a problem getting pregnant. I've had three pregnancies one successful two unsuccessful, none of recent though it's been over 4yrs. Long story short I'm two days late have had two negative pregnancy tests. I've always been regular and on time... Only symptom I have is sore tatas. I'm alway tired so I can't go judging off that.
