Prochlorper medication for nausea?!

I’ve had severe morning sickness this round (2nd pregnancy - 11 weeks currently). After a few different scripts, my doctor pulled me off of Zofran and put me on Prochlorper.

The good news is it’s working for me so far, but I’m nervous as the medicine comes with pregnancy warnings I guess. I called in asking for more Zofran and the nurse told me so I haven’t gotten to talk to my doctor directly about it. I trust her, but I’m nervous with this one.

Anyone have any experience with it?!

Thanks!!!
