14 dpiui spotting but no AF

Anyone else have spotting with their <a href="https://glowing.com/glow-fertility-program">iui</a> and then get a BFP? I tested 12 dpiui and it was negative. Light brown/pink spotting for the last two days but nothing else. Help?!?!

Spotting in general before a BFP....likely or not?

Any experiences similar to this?? Please do share.
