hi you will have to wait to see if you miss your next period if you do then get tested its just a waiting game. but for me your app could be a tage out ovulation day shoud be around 14 days after the first day of your period give or take the odd days and you b/f would have needed to have had sex around 2 to 3 days before that its takes our men 3 days to reach your egg. hope this helps you. good luck
