Worried something is wrong... advice needed!!!?

i am now 10 weeks pregant and had a scan when i was 8 weeks and 2 days, i had lots of feeling sick, headaches and tiredness and tenderness but the last week that has all gone except a lil bit of tiredness. sometimes i forget im pregnant as im startin to feel normal. i had a miscarriage in january which started as bleeding. i have had no bleeding other than a tiny bit of spotting after . is it normal for these symptoms to disappear and still be a healthy pregnancy???
