Anyone ever been more than 2 weeks late and gotten negative pregnancy tests but ended up pregnant?

I’m currently 17 days late, took a pregnancy test at 10 days late and it was negative. I went in today to get a blood pregnancy test and praying it comes back positive seeing that we’ve been ttc for over a year now

I’ve been getting these weird feelings in my lower abdomen and left cervix area. Really bad headaches. Mild cramps that come and go. Craving foods i don’t usually like or eat. Mild nausea. Just haven’t been feeling like myself lately and definitely no sign of my period coming.

Please help😭
