I took one on Saturday the 14 also and there was a faint line but not as dark as the first 2 days before. I had sexual intercourse on Thursday and Friday but not Saturday. Was I supposed to have sexual intercourse on Saturday also???? Also was Thursday and Friday the days that I ovulated since Saturdays test came out a faint? I'm so confused. I ovulated very late this month so I'm confused about these ovulation test HELP PLS?
