I had a pre-pregnancy check up, to get a full blood screen and to see whether all my immunisations were up to date, so I could get them all done before possibly being pregnant.

Particularly rubella.

Also checking things like your vitamin D etc which may not come up with normal tests.

Getting your pap smear done (even if it's only been a year) is also a good idea, so you're not possibly needing it while pg.

Good luck
