Oo, normal lang yan sa pregnancy sis! A few of us experienced it around that time too, the hormones and baby's movements kaya nagiging sensitive ang tummy natin. Make sure you're drinking lots of water para hindi ka madehydrate, and stick to bland foods muna like congee, banana, or crackers kaya madali sa digestion. But honestly, if it persists for more than a day or two, or if may signs ng dehydration (dry mouth, dark urine), better check with your OB na lang para sure and peace of mind!
