Anyone experienced this? Pregnancy test line getting darker for 2 months, but suddenly got period?

Hi everyone! Just wondering if anyone has experienced something similar. My last first day of period was on 12 August 2026, and I’ve been taking pregnancy tests almost every day throughout October. At first, the test line was very faint, but over time, it seemed to be getting more visible. I noticed that when I tested in the evening, the results were always negative. However, when I tested using my first morning urine, the line appeared much darker. This morning (20 October), the test line looked noticeably darker than before, just like in the picture. But the strange thing is, I got my period today! 😭 It’s been about 2 months and 8 days since my last first day of period, so I’m really confused. How can the test line seem to be getting darker, especially with first morning urine, but then suddenly I get my period? Has anyone experienced anything like this before? I’d really appreciate hearing your experiences. I’m so confused right now! 🥹
