No I wouldn't.... It would technically be safe to have the HAV, HBV and tetanus/diphtheria and pertussis vaccines as they are not live, however with pregnant women it's better not to have anything if you don't need it.
MMR and VZV are live so a big no no when pregnant. It's only a hypothetical risk but still not one to risk.
Te policy that you have to adhere to in NSW( is that where you are?) has an opt out clause for people who have a medical contraindication to vaccination.
Pregnancy would be one. If your results come back that you need vaccinating get you GP to write a letter saying you have a medical condition that prevents you from being vaccinated at this point and you will vaccinate when medically safe. TAFE/UNI's can't turn that down.
PM me if you have any questions. This is my field!
