metformin and aspirin in pregnancy

Mommies, has anyone been prescribed metformin and low dose aspirin (for their GD) during their pregnancy before? I had just started taking metformin and I am already having loose stools (which feels good though coz I always have constipation). Is this normal? But I am just worried if I ate aspirin it will become worse. Anyone tried eating these 2 during their first trimester?
