The dobutamine stress echo test involves the injection of a medication called dobutamine while you are closely monitored. The medication stimulates your heart in a similar way as exercise. Important: If you have a pacemaker/defibrillator, it must be checked at Cleveland Clinic before your dobutamine stress echo test.
Your Baby During the Second Trimester. The second trimester is normally considered to be from the beginning of the fourth month to the end of the sixth month. This works out in weeks to start from about the thirteenth week of pregnancy.
As you enter your second trimester of pregnancy, the morning sickness and fatigue that plagued you during the last three months should be fading, leaving you feeling more energetic and like your old self again. The second trimester is, for many women, the easiest three months of pregnancy. Take the time now, while you're feeling better and your energy is up, to start planning for your baby's arrival. During the second trimester, your baby is growing quickly. Between your 18th and 22nd week of pregnancy you'll have an ultrasound so your doctor can see how your baby is progressing. You also can learn the sex of your baby, unless you'd rather be surprised.
