Random vomiting

Jazzmiin👩🏾‍🦱👶🏽👱🏻‍♂️

So I've been having really bad headaches and I didn't have morning sickness in the 1st trimester only during the 2nd trimester. I just made 20 weeks and I seem to have a vomiting episode at least once every 9 days or so. Is this kind of cycle similar to anyone else's experience?
