Ovulation test??

Sara

Okay so I don't wanna sound totally stupid lol but I've never actually used ovulation test for ttc well I just got my kit in the mail today with my Ovulation test in it I did start my period today do I start testing as soon as I'm off my period??? And do I test everyday?? And if i get a positive does it mean I'm ovulating at that time or I will in the next day or 2??? Also how do I know when its the time to BD?? I'm sorry so many questions just wanna make sure I do it right lol.😁
