I somtimes hate using these apps. I understand they are not accurate and you have easily ovulate later or earlier than expected it just sucks when multiple apps are saying your late and you are just waiting there like hello can you show up already if you are going to show up! Lol its just frustrating seeing the apps say you are late and fighting the emotions. Every single time aunt flow is late i hype myself up like maybe this is my month. Than get so disappointed when aunt flow eventually arrives. So im trying so hard not to let my mind wander especially because i took too test that were both negative. One of the 16th at night and one on the 17th. Which does just make me think i ovulated later but than a small voice says your not out till aunt flow arrives. Ughh
