9DPO and BFN 🤦🏽‍♀️ could I still be pregnant

Bu

So I took a test using FMU and it was completely negative. Not even a hint. I would of thought that if I was pregnant I should start to see a vvf line by now? Anyone else had this but still been pregnant? I know it’s crazy but I just feel so pregnant or maybe my mind/body is playing tricks on me
