When is the best time to have sex when your ovulating?

Ok so I’ve been googling stuff every single day to find out when is the best time to have sex because glow told me my ovulation day would start on the 19th of this month but I just got my I believe somewhat positive today. I’ve been having intercourse literally everyday because idk what I’m doing some one please help. I downloaded this app and the app called Flo but this app has been more accurate so should we try again tonight to make sure it’s sticks because I’m not sure, and I don’t want to get Bv🤦🏽‍♀️
