Girls!!! I’ve heard that every day baby dancing can make your chances of conceiving less because your partners sperm count can lower?

I’m due to ovulate on the 1st March meaning one of my highest chances of pregnancy is 28th! I don’t know if to BD 27th, 28th AND the 1st or just 28th/ 1st? I don’t know... and would appreciate any information! We have BD every other day throughout my cycle so far, missed yesterday so due to BD today.

I’ve googled until my hearts content but the opinions are SO mixed I don’t know what to do. TIA x
