new to OPKS help please!

Hello! This is my first time using an opk throughout this whole ttc process and i know that the line has to be as dark or darker than the second line so I guess I’m not ovulating yet? My period ended on sept 22 and glow predicts my fertile week begins tomorrow. The strange thing is is that I’m spotting today. Is that from ovulating? If you ladies could please take a look at the opk and let me know what you think, any tips and advice is greatly appreciated! Thank you in advanced!!
