Long post...but confused...TMI

Ok so this is my first month using opk. I got a positive test on Wednesday morning. My app originally said that Thursday Friday and Saturday would be my most fertile days. My husband and I BD on Sunday, Tuesday, Wednesday and Thursday. When I put the results of my opk in the logs it changed my fertile days to Monday, Tuesday and Wednesday. But on Friday and Saturday I noticed a stronger smell coming from my lady business which my OB told me was most like Bc of ovulation. So my husband and I BD again Saturday night. I’m so confused we tried so hard to not miss the fertile window but things seem to be all over that place. When do you think was the actually window and do you think we hit it?
