Not sure how I feel

Kisha
So I went to the doctor today and I got a BFN I have never missed a period it is like clockwork. She took blood work and schedule me for a vaginal ultrasound because I keep having pain in my pelvic area on both side and bad back pain. I wanted to be pregnant so bad and to top it all off AF is 11 days late. Feeling a little frustrated.....😔😁
