I’m no expert on astrology or zodiac signs, but I’d maybe suggest the threads on birth moon phases and birth chart signs.
I think you can probably get some guidance out of your signs. It’s certainly helped me understand some things better, but I don’t think they work as any kind of test. I think any combination of zodiac signs can be twin flames, and your signs might help you understand one or two aspects of the journey (maybe more), but I don’t think that a combination can confirm or rule out that they’re your twin flame.
My understanding anyway.
