Late period!

KC • We have a wonderful 10 y/o boy and now waiting for our gift from God in September 2016
Hey Ladies!
I'm four days late, however I took a test yesterday and it was negative. I was wondering how many dpo were you when you got your first positive pregnancy test
Every time I tell Glow that my period is late, it shifts everything, so now it says I'm 14 dpo (rather than 18dpo).
Please let me know!!! Also, what symptoms did you have. I feel pinching sensations and sore boobs
