Yes, as long as she’s still around as a ghost. Otherwise what you contact is more like an astral copy of her energy that you are evoking.
If she’s moved on to another incarnation she is unlikely to consciously understand that someone from a past life is trying to contact her. The person she is now might get dreams or a feeling of being watched, but won’t have any frame of reference to put them into context. Assuming she’s human, that pesky “veil” thing kind of gets in the way there.
It’s so soon it’s probably that she hasn’t moved on yet.
I would caveat that in many traditions, it’s believed that if you try to attract the ghost you can prevent them from moving on and stagnate their spiritual journey. Or worse cause them to attempt to cling to their qi body which turns them vampiric. There’s traditions that have rules like “do not mention the departed’s name for a year” to try to avoid holding them back.
This is the reason the Chinese call ghosts “hungry ghosts” and how the myths of vampires started. As ghosts need human qi - which they no longer have a physical body to create for themselves - they start to take if from the living. In this case that could be you. This can cause illness and stress, obsessive thoughts of the departed and overall be harmful to both parties.
On the other hand many ghosts have a lot of fear about moving on, or they just want to cling to the living to “live” viscerally through them. There are ghosts of addicts that hang around the hospitals they died in that attach like parasites to patients and make them addicts (ref: “The Unquiet Dead” book)
Another circumstance where ghosts are retained on purpose are the spirits of lineage masters in martial arts or spiritual orders. These people are usually expected to be adepts of energy working and are able to sustain their ghosts without resorting to vampirism, but are assisted via offerings. This is why offerings as a practice are used in the occult even for the entities that don’t need it as as they are not ghosts.
Without taking energy from humans she will fade and die the 2nd death sooner or later - also called “moving on”. You can continue talking to her but at this point you’re talking to the recorded copy or “shade”.
Unless… you use time travel intentionally in meditation, then you can go back to talk to her spirit at another point in time, but again she will not be overtly conscious of this, though her subconscious will know - and if you do this then you already did it and you might have seen the signs while she was alive.
