Is there a chance?

So I’m a very aware person, I started a new bc pill in June and haven’t had bleeds since. I also don’t know when I ovulate. However, I had unprotected sex on the 26th of August, withdrawal method. I have been experiencing some symptoms like pinkish/brown discharge, fatigue, awareness for smells and queasiness but I am unsure if its not my mind playing tricks on me. I’m supposed to start AF next week Wednesday, should I wait and test then??
