Help with translating lyrics

[jim100]

Hi,

First post here. I've been a life long learner of Spanish with a haitius for the last year or two. Could you help me with translating these lyrics from a song sung my the Mexican singer Lucero?

Por eso hay que luchar cuando se ama de verdad
Y ya luego que pase lo que tenga que pasar
Porque un amor así, no es fácil de encontrar

I'm having trouble with a translation of the sentence "Y ya luego que pase lo que tenga que pasar." What I think this verse says, translated into English is;

That's why you have to fight when you truly love,
and what happens will happen,
Because a love like this is not easy to find.

I guess I'm having trouble with the use of "Y ya luego que."

Thanks so much in advace!

Jim
