Okay my AF was June 25 -29

My husband and I had shower sex on the 26, 28, and 29. Since I was lightly spotting. My dr told me I couldn't get pregnant on my AF (which now I know is false) we had sex on the 30th which in one of the period trackers I downloaded said the 30th was a fertile day for me. I have had some spotting but very light and was wondering if you guys could help me figure out the possibility of being pregnant or conception.
