Is there any Islamic basis for this? Are there other days/dates that should be avoided for physical relationship between couple?

When trying for a child, I have heard that there are certain dates that should be avoided for intercourse.  For example the 14th, 15th and 16th of the Islamic months should be avoided in order to have a healthy baby.  Is there any Islamic basis for this?  Are there other days/dates that should be avoided?

Jazak’Allah Khair

In the name of Allah, Most Gracious, Most Merciful

Assalaamu `alaykum waRahmatullahi Wabarakatoh

There is no Islamic basis for avoiding intercourse on certain days to have a healthy baby 

And Allah knows best
