So frustrated

Autumn • My beautiful son born 5/26/19 💙🥰❤️😍
So I'm now almost 8 days late for my period. I called my gyno yesterday and asked them if I could come in for a blood test because I've been getting negative hpt and still no sign of a period, they said sure come tomorrow morning (today). So I come in they make me do ANOTHER urine test which of course comes back negative and then the nurse tells me to go home because I'm probably just stressed and that's why my period is late. 😡🙄 my period has never been late before and I wasn't stressed about anything until today! At this point I don't care if my period comes I just want some answers. 
Sorry for my ranting.
