I am not glad you had it but glad to hear a similar experience. I have terrible anxiety so it's hard for me to shrug it off. It makes me constantly paranoid it will happen again and also makes me worry that it could be a sign of some terrible illness unrelated to the pregnancy!
I had the exact same thing and was exactly the same way, always super paranoid.
Toward the end of my pregnancy I was super dizzy a lot and even got the whole seeing stars thing & was constantly nauseous again. I had myself convinced I had pre-e or something terrible but nope, I was fine just need to drink lots of water and make sure to keep your blood sugar levels up. The Dr's are seeing you on a weekly basis now and will more than likely catch anything so just try not to stress but I know it can be hard! :)
