When to BD?

RR • Together since 2009 | Married since 2014 | TTC since January 2015 | 3 M/C`s | MTHFR | Baby girl due 06/27/17💗
I just started using the Clearblue fertility monitor this month and I got my first high today. 
My question is how often should we BD? I read every other day and I also read every day. 
Some say that every day will decrease mobility or something in the seamen but some also say that it's better to BD during the entire fertile window.
