Pregnancy Info HOME

This is probably a stupid question. But this is my second pregnancy and I've gained about 5 pounds already and look about 3-4 months pregnant when i know im only about a month or two. I took a blood test last week to confirm my pregnancy and don't have an appointment until the end of the month. so im kind of concerned about it because with my first child you couldn't tell i was even having one until i was 7 1/2 months and even then i looked about 4-5 months.im not a fat woman im 5"6 and am normally about 174 lbs.and i have always had a flat stomach so it's obvious. should i be concerned so big so soon?
