Chance of pregnancy?

My cycle after birth control for the last four years has been semi regular with one 50+ day cycle in one 12 month period (we’re looking into pcos). The first day of my current cycle was June 22nd and my period ended June 26th. We confirmed ovulation on July 6/7, had sex on July 3 and 7th, and I started spotting on July 13-18th. My periods almost entirely consist of bright red blood and are actually fairly heavy in the beginning, so at most the bleeding/spotting was only ever super light compared.
