Congrats on your BFP.
I also use Blackmores Gold Pregnancy and Breastfeeding vitamins. if you can, price them out at a discount chemist, as they can be loads cheaper, and if you are planning on b/f, and they have them on special, then stock up!

I also take an extra magnesium tablet for cramps etc, some peoples do take a magnesium & Calcium mix.

You will be rattling by the end of your pregnancy!
