how often should be BD during fertile window?

Just wondering if you ladies have any input. The <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> says every day during your fertile window, but then I've seen posts here saying that their doctor said every other day. We are on our 2nd month TTC and today is supposed to be my most fertile day (although my ovulation test isn't quite positive yet) and we BD last night.
