Ovulation help

Alicia • TTC after miscarriage July 6 2015
Help please! I miscarried in July and have never taken an ovulation test before. Lol I have two apps one says I'm in my fertile week now another says starting next Tuesday so I took this test just to see. Its 645 pm here so this is not from my first morning urine (does that matter?) Its obviously faint but I do see a line. First day of LMP was Sunday August 2 am I in my fertile window now? I have more ovulation tests do ibtedt again tomorrow? Or the next day? Also got soft cups last night plan on using them.. thoughts?
