I've also got the ipregnancy one & found it to be the best

I have two others - Foods To Avoid While Pregnant & What To Expect In Pregnancy.

The What To Expect In Pregnancy one is quite good, and also has daily tips/info as well as weekly... and has an added forum to it (I've read, but haven't posted).

I guess the only thing if anything that I don't like is that its American (so especially in the forums) some things are a little irrelevant as they obviously do things a little different in regards to the health system/Obstetricians etc.

The Food one is quite good - gives you a list of foods that are safe (ie what cheeses you can & can't eat, etc) and it gives them to you in sections - cheeses, seafoods, meats, drinks etc etc
