18m sleep regression or something else?

The past 2 nights Ava has been waking up around midnight crying and screaming. When I go in she says up up up and wants me to hold her and she kept looking around the room scared and panicked so I think it could be night terrors? I reassured her she was okay and safe and that we can see her on the monitor . I put her back in her crib and she instantly starts crying. I give her a few mins and she goes back to sleep. She’s been such a champ at sleeping 7-7 puts her self to sleep independently so I’m just worried if this could be something else like health related ? She is teething molars and k-9’s are coming in and we did give her a little Motrin last night thinking it could be teething pain but she still woke . has anyone experienced anything similar?

Pic for cuteness since I hardly ever post - we went out on a walk the other day and she was so happy she loves to be outside, obsessed with rocks 🪨 and listening out for airplanes ✈️.
