Sometimes it can take up to six weeks for a drug to take affect. Stopping cold turkey is not good. The best thing to do is talk to your doctor before stopping any medication. Most mental health medications you need to ween off of. Good luck.
Out of your system it is but it doesn't mean it doesn't affect your brain chemistry anymore. No withdrawal symptoms so far so good and don't expect to have any.
I would not say the same to someone who had been taking Zoloft for 6 months and more since the withdrawal symptoms can start after 1 week. The therapeutic lag is also present when stopping. Your brain chemistry didn't adapt to the medication therefore suggesting there would be no withdrawal symptoms for you.

It's not possible to tell you with any accuracy short of a blood test maybe.
If you haven't had any withdrawal symptoms by the next few days then I doubt you will.
Good luck.
