Are you spotting or bleeding or cramping nicolette? These things combined with a lack of symptoms make miscarriage a greater possibility, but even then, most women who bleed while pregnant actually go on to have a normal pregnancy and a healthy baby.

None of us can see inside you, unfortunately (i wished i had a zip to make sure everything was fine in the early days of my PG with DD LOL), but if your only concern is that your symptoms are lessening then everything's probably fine. With my 1st m/c i never HAD any symptoms of pregnancy, and with my second the pregnancy symptoms continued a week after i'd miscarried. These things aren't linear.

If you're worried, call your Ob, it's his job to make sure you and bubby are ok.
