As you are rhesus -ve you'll also have a bt for antibodies.  So far I've had them at the beginning and at 28 weeks and will have another bt at 36 weeks. They don't automatically give anit-d anymore.

The main rules I've worked to with regards to foods.

Have been making sure what I eat is hot and cooked, avoiding anything with raw egg, undercooked meat, cold meats and anything that is left sitting around luke warm. Ie: chinese takeaways, indian etc.
The main culprits for listeria and salmonella are dairy products and eggs.
I was pretty vigilant during 1st tri too as I was paranoid of harming my baby in anyway.
Its only 9 months which isn't all that long in the general scheme of things.

Big congrats and there isn't anything else you need to do your MW will organise bt etc. Do you know what your blood type is?

NZFood Safety have a list of foods that http://www.nzfsa.govt.nz/consumers/low-immunity-child-pregnancy/pregnancy-food-safety/ are ok to eat during pregnancy.

My Mw essentially told me to avoid the deli counter at the supermarket, same with seafood, sushi etc.

Never had MS unfortunately I think you either get it or you don't. I did find eating small regular meals kept the nausea at bay, marmite on toast in the afternoons was my saviour in the first trimester.

Are you taking FA?
