Overwatering vs underwatering is really hard to tell. 3 months is plenty for the plant to bounce back from any root damage while repotting.
Underwater and you plant cant get enough to drink. Overwater and your roots rot so the plant cant take in enough to drink.... you cant tell from a picture. If your pot doesnt have drainage holes then youre really in trouble when it comes to watering.
My advice is to go get a moisture meter ($5 on Amazon) so you can be sure.
