Sayang, blood in urine during pregnancy needs to be checked by your doctor, please don't wait, go to your clinic or hospital asap, okay? It could be a few things but only a proper check can tell. A few of us mums went through UTI scares during pregnancy, and the doctor sorted it out quickly once we came in. Jangan worry sendiri, your baby needs you to get this checked properly. Minum air is good, tapi ini kena see a medical professional, not something to manage on our own. Hang in there!
