Af so late. Pregnancy test Bfn

Phylicia • Trying for baby #2 while breastfeeding 😜
My af was due 6/17. I got nothing glow keeps pushing my af back every two days. My pink pad apps says i am 7 days late. It calculated a different day to start. I tested yesterday night and bfn. So i should wait the rest of the month out i think. I've never had this happen before.
