I'm 7w 3 days pregnant and have been horribly nauseous for about two weeks now, I keep eating carbs and cheese etc to keep the nausea at bay. I've gained 2.5kg already!! It seems that pregnancy weight gain might be partly because of this horrible nausea problem...AIBU? any tips to stop gaining so quickly? I'm scared I'm going to go into the second trimester having already gained 10kg...
