What about tap water?

I am a big soft drink drinker, obviously want to cut that out now and replace with water, but I dont want to buy bottle water all the time!

Is tap water (in melbourne) OK to drink or should i invest in one of those filter jugs from kmart??

No more beer for me! And I am VERY proud to say I quit smoking 1 week before we conceived - isnt that timely!!

p.s. I cant stop noticing these cramps I am having - if anyone has more detail for me, most appreciated. They are pretty much like period pains but now more... direct? I wish I could explain them better. The are not strong, easily bearable and not comparable to period pain I have had before - should i expect them to slowly disappear over time?
