Is it ok to get veneers replaced and my teeth whitened at the dentist whilst pregnant?

I am 17 weeks pregnant and I've only recently found out I am pregnant. I have had my appointment booked for a couple of months now. I don't exactly need to get it done as it's not like my teeth a rotting but my veneers need to be replaced, albeit I could probably go a couple more months before they really need replacing. Is it safe to get my veneers replaced and my teeth whitened whilst pregnant?
