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.
Hereâs the most common breakdown, along with official weeks from the American Congress of Obstetricians and Gynecologists: First Trimester: 0 weeksâ13 and 6/7 weeks (Months 1â3) Starts with the first day of your last menstrual period (LMP) and ends with the last day of the 13th week thereafter. During your last period (which will be your last for a while), your uterus is preparing for ovulation and your body is gearing up for pregnancy, so technically, you can start counting from this point. Second Trimester: 14 and 0/7 weeksâ27 and 6/7 weeks (Months 4 â7) Starts at the beginning of the 14th week after your LMP and lasts through the 27th week of pregnancy. Third Trimester: 28 and 0/7 weeksâ 40 and 6/7 weeks (Months 7â9) Starts at the beginning of the 28th week after your LMP and ends with labor.
