Yes,
0nly + or - 3 days to and from 14th day are fertile.ie 11,12,13,14,15,16,17
However,this is applicable to only those women with regular cycles.
One can use the rythm method (used by our grand parents) and avoid the 6 days but the problem is;
Increases promiscuity-the man will outsource someone to service him the 6 days incase of hyperactivity....those with excess level of testosterone.
Irregular periods due to stress,other drugs induced eg hormonal category.in this case,the lady the cycle is distorted.
Women-this is the time they are sexually active due to increase in hormonal levels.....temperatures and mood......(how do you deny her the sugarcane....?)
