There are so many different opinions of 19 weeks being 4 month and 5 months which one is it really?

I have my doctors appointment this Friday coming up ... I definitely wanting to ask her directly but I feel like I should know this by now ... but I've searched it up like so many times and it just back and fourth from 4 to 5 months ... anyways any opinions on this?... So is this correct?
