Anyone experience this before?


So i took a test and it came out negative (10 dpo) but i was at work all day and took the test in the afternoon so it’s not morning urine. And I drank a lot of fluids while I was at work and when I peed in a cup I had very little pee that I had to tilt the test to get more on the stick, I don’t know if this can affect the result to be negative , has this happened to anyone before? And then got a BFP a day or two later ?
