False negative pregnancy test

Has anyone experience no period for more than 10 days of your expected day of menses but also with false negative pregnancy test for that entire period with no menses? Cuz I'm currently experiencing this and this was my first time it happened. Yes, I do had sexual intercourse before recently and with no contraception used. Was actually hoping to see positive result or even a faint positive line but don't want to be too hopeful yet disappointed too. So would appreciate if anyone can share if you had the same experience before or recently, and what was the result? Seek for an advice 💜🙏🏻
