6 days late but negative pregnancy test on 4 days late!

So, my periods run like a clock. I just got married and we weren’t trying but we’re not not trying ☺️ Been feeling possibly pregnant but might just be pms. Period is 6 days late. I took a test at one day late and 2 tests on 4 days late— all negative (was low key disappointed 😔) Is there any way that I might be pregnant? Anyone have a similar experience? Looking for hope but also looking to be told I need to get off the bench and keep trying if that’s what you ladies know 🤣 thank you 💖
