With my son I didn't really start to show until 26ish weeks, If the doctor says everything looks good and your measuring alright then things should be fine. As for the fluid, if your really worried about that I heard drinking more water will help with that.
As for the ticker, when you go to the site and make it, they'll give you 3 codes to use. Take the one that says BBCode, copy and paste it into your signature block and it should work. You need the entire code they give you for it to work, hope that helps.
