So I'm cd 32, 13dpo an AF is due today; bfn this morning. All my temps are above cover line. Cervix is med/high, soft (like it's apart of my vaginal wall) and lite creamy cm. 
Curious if anyone tested the day AF was due and got a negative and then received a bfp later on?  
Thoughts and opinions appreciated. I'll include my chart. If you'd like to share yours id love to see it!
