Sad I need advice

Sarah • 33 years old FTM.
So this last month I got spotting around the 16th of September lasted two days it was very light and thought it was aunt flow. On Monday  of the following week af came which I knew she would come. Which is fine she lasted till Subday Monday we didn't have sex but we did last night and Glow is telling me I was ovulating. Can you ovulate the day after AF ? or while you have it? I really wanted to ttc this month and before I could prepare  I lost the opportunity ....my cm is still a tinted tan from AF and I didn't have the egg yoke mucus you should have while ovulating. Could glow be wrong?....do I still have a chance to ovulate before AF?
