About 15DPO, no AF, no BFP

Hi Ladies,

so I really thought I was pregnant this month. I've had a lot of symptoms that don't match up with a normal cycle for me (nausea, constipation, light cramping at odd cycle points, sore breasts). However, today is supposed to be the start of AF. I have had no bleeding, no period cramping, and no positive test. I think I'm 15DPO, but maybe only 13DPO. My periods and symptoms for those periods are normally like clockwork, I've tracked dates for about a year and my only symptoms are usually back and abdominal cramping.

What's the latest you got your BFP? I'm just going to keep waiting on AF, but I was hoping to hear from some other gals. Thanks in advance!!
