I have been charting for a few months and generally around this time if I am seeing thos at 12 dpo (ish, i dont think this app know my exact O date) I know this is bad news. I am wondering if anyone has ever had a BFP after a several dat liteal dip. Looking for a small amount of hope before my period shows up. This was our first <a href="https://glowing.com/glow-fertility-program">IUI</a> and i am monitored often by the clinic to track ovulation, hence why i think this app is off by 1 day.
