I am tracking my ovulation since last 8 months and no success yet in BFP

I am BD on every fertile days of my cycle and doing BD twice on my ovulation day as suggested by <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a>.

I am just curious to know is it necessary to track ovulation and wasting money on ovulation prediction test stripes.

Can't we do BD on entire days of month excluding just your period days.

Who knows might any day it works.

Why everyone is wasting money just to know when they are ovulating..cnt we maintain relationship through entire days of month

I really badly need advise on these my pretty ladies..Please help me
