I suggest getting your BP checked as could be pre eclampsia.

Good luck
I had that, when I had issues with my blood pressure.

Definitely call and arrange a check up, just in case.
I get the falling stars when my blood pressure is up and its quiet common to be a symptom of pre eclampsia so if it happens again be sure to get checked out. Also possible to be dehydration. Goodluck I hope its nothing
