When you were born, Yayathi had children simultaneously.
But, they weren't enlisted.
That is why the bloodline is empty.
Which means, Yayathi should've had daughters only.
In that case, that bloodline should've ended with that generation.
Hence, there's no chance of girls being born in your bloodline due to the curse.
So, you should be having boy children only.
The result of the curse is a girl child.
You had a girl child 3 consecutive times.
What exactly happened in your bloodline?
