Yah, actually very normal in early pregnancy! Hormones slow down your digestion, so constipation is super common, a few of us went through the same thing and initially thought something was wrong. Best thing is to drink lots of water, makan makanan high in fiber (oats, fruits, veggies), and maybe do light walking or stretching; if it continues or gets painful, do check with your doctor to make sure all is well and they can suggest safe options for pregnancy. Jangan worry too much, this usually improves after first trimester!
