I need help trying to see why I am spotting again this month

Patient: I have a question. I started my period on the 5th of this month until the 7th. I was fertile from the sky 10th- 16th. I ovulated on the 15th I’m pretty sure and had intercourse with my husband on the 11th and the 17th and now it’s the 29th and I’m having very light cramps and spotting pink. Could you help me to try and figure out what is going on just until I can get to the doctors
