Shaking movements

AK

For the past month or so I’ve been feeling shaking like movements from the baby. I brought it up to the doctor and she said until birth they wouldn’t be able to tell me anything. It has decreased.. but it’s still happening and obviously she’s stronger now so it seems worse. I’m trying not to worry but I have never felt this with my first and I’m getting more worried everytime it happens. Does anyone have any insight on what this could be? Honestly it feels like she is having a seizure, I hope that’s not the case but I can’t figure out another reason for it...
