The fifth week

If you did not have any signs of pregnancy last week, you should expect it this week, which is the fifth week of pregnancy. If your breast hurts, you get tired quickly or you have to go to the bathroom constantly, take these symptoms seriously. Your body produces more blood this week to deliver oxygen and food to the baby. The heart rate increases to maintain its balance and this increase brings fatigue, confusion, and headache. This week, breast pain or a tingling sensation will bother you. There is also a possibility of breast enlargement and darkening of the color halo around it. Your baby's heart starts beating this week. The neural folds (tissue folds that become the brain and spinal cord) are connected and this means distinguishing the head from the tail. Also, the embryo is similar to a frog. Your little one is 9mm, the size of a fingernail right now.
