Very confused

Supposed to start my AF on the 14th or 15 September but I started on the 16th ended on the 18th my husband and I had intercourse during that week until the 22nd and I spotted on the 21st and the 22nd I decided to take an ovulation test on the 23rd and keep on taking them until the 29th which is a total of seven days some days the line seems darker than others and during that week I was actually having intercourse with my husband every other day to make sure that I was to become pregnant I have never taken a ovulation test to become pregnant with my first four children
