Has anyone not gotten a positive pregnancy test until after their missed period?

I’m not supposed to have my period until next week but I have been trying to conceive all this month and even have sex many times around and on my estimated ovulation date. I have tested multiple times and got a negative pregnancy test. I’m hoping that maybe it’s still possible. Just have to wait until next week to find out.  I have more and more symptoms every day like nausea heartburn indigestion, dry skin, extra thirsty, waking up in the night, hungry etc. Has anyone had any luck in this same situation?
