Thank you ladies for reading this post and those of you who can relate or have experience

My period was December 11-16, so accordingly the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> my fertile window was the 21st to the 27th. On the 22nd I started spotting up until yesterday. Today I haven’t seen a whole lot. This has never happened so I am a bit concerned. This picture below is how it started, but for the past few days is has been brownish I would say... thoughts ladies, please
