Ovulation/tww

Me and my partner had insemination the day of insemination on the <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a>.. when testing said wasn’t ovulating. The next afternoon said she was ovulating but later in evening when she checked the line faded and the next morning the line was gone completely.. dunno what it means!!!
