HELP ME

I really need some help. I got my period November 6 to Nov 10. My boyfriend and I have a couple of stokes of unprotected sex on November 15 with no ejuculations, idk about Precum.(not even a minute). All the other days were full protected with condom and he never ejuculated.  My fertile window on the 18th to the 24. The past couple of days I had watery cm and today I have glue like,thick, creaming cm. which I think means I ovulated already. What are my chances of being pregnant at this point? Please help me
