Congratulations on TTC #2!

I agree with the PPs but thought I'd add that (if you haven't already) now is a great time to learn 'your' body and cycles. Fertility friend is wonderful for learning the basics and tracking it all to make it easier to see patterns etc so you'll be more likely to know what to expect and when once you are actually TTC. Blackmores is meant to be quite good. They have a pg & BFing formula which are gel coated liquid capsules absorbed easily, or a pre-concieve which has both a gel cap and normal (massive) tablet which I don't know how well all women break down and absorb. Apparently the only real difference in the two types is that the pre-concieve has a higher dose of copper so its recommended you switch once pg... Could be a pain if you become pg quickly and 'waste' a pack coz they are expensive??
I really hope it all goes well and you're welcoming another little one next year
