Krystal...
I had a pap spear when I found out I was pregnant. And I was 38yo and it was my first pregnancy... so I was a bit nervous about it.
They do it a slightly different way... not go so deep, or use a different implement?

It is safe... and it is better to do that, then find out you've got something that is going to harm your baby. The pap smear is for your babies sake - not necessarily yours - when your pregnant. Not that I'm implying you've got something... but best to get the all clear.

I've no idea about rubella.... so I would be talking to your doc about that too.
