Fish, you see.. Told you this week is your 17 weeks already coz I have that apps too and I know you are few days earlier than me, so I aga aga know you week 17 this week loh. hehe....
allets, so far I only find this "What to expect" good and FOC. There is another apps I downloaded "My Baby Pregnancy", similar to WTE but then have to pay for it. The info is slightly different in content. I will read both everytime to get more info. If you don't mind paying, you can download that. Another apps I find the Q&A informative is "Preg411" Got qns and answers about pregnancy. FOC I think.
Now I slowly downloading baby games, learning apps.
