Is this a concern?

I’m 7 week pp but this started happening while I was pregnant. It started when the California earthquakes happen. I was near the area and on a second floor so i felt it pretty strong for being my first experience. Ever since then randomly while staying very still standing or sitting I feel as if it’s that exact day of the earthquake. I get dizzy. It hasn’t really bothered me but it’s becoming an everyday thing and I’m starting to get worried. Was it because i was pregnant while it happened?
