Feeling hopeless

On 11/28 I woke up with sore breast so I took a test and it was positive. The next morning I took another test first response which was positive too. Fast forward to today 11/30 I wake up and my breast are not tender anymore at all, I took a test and it was still very faint but this time I took a clear blue. I hate that I always test before my missed period. My last period was nov 3 so I still have to wait 3 more days to see what happens. I feel like I’m no longer pregnant and that will hurt my heart again! Thinking about it it doesn’t make sense too because the app says I have a 33 day cycle and the app is expecting me to start my period nov 6. Here’s the clear blue test I took does anyone have any input or had this happen before? Also I think I have a uti which I’m thinking is affecting the test😫
