Hi Bernard. since your re-entry to KSA is still valid you can use it. You can travel from Qatar to KSA which is more cheaper for you to do than going home to Philippines.

I did that already when I visited a friend in Qatar while working in KSA. Hassle FREE.

If you are holding valid working visa here in Qatar it doesnt matter at all since you have valid re-entry visa in KSA and your IQAMA is still not expired.
