2-4 days late..... TTC

Victoria • Hello, my name is Victoria. I have a beautiful 3 year old little boy. Me and my boyfriend have been together for 2 years and we have been trying for a baby off and on for a year.
I haven't been tracking my symptoms or anything this month its been a crazy month. This morning I look at the date and it hit me that I haven't started my period yet so I go to my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> and see and it says I'm 4 days late. I always get tender sore breasts 1 or 2 weeks before my period and I have sore breasts but that's the only symptom of my period or pregnancy I have is sore breasts. So could I be pregnant or no? I'm also using a nothing app and it says I'm 2 days late I'm a lil confused. But got my fingers and toes crossed that this is my month
