I heard that cholesterol goes up regardless in pregnancy..therefore anyone is at risk for developing blood clots because increase of cholesterol.true?

Cholesterol /= clots: There is increased risk of blood clots in pregnancy, and there is an increase in cholesterol in pregnancy, but these 2 are not related. Blood clots are due to stasis (still) of blood, and not due to cholesterol. Blood clots in pregnancy are due to the increased estrogen, less mobility, and sometimes the uterus blocking a blood vessel. The cholesterol increase in pregnancy usually is benign.
