9 weeks of pregnancy is about 2 months and 1 week. Pregnancy is counted from the first day of your last menstrual period. The first trimester lasts until 13 weeks and 6 days of pregnancy.
A first-trimester ultrasound may be recommended, often between 11 and 14 weeks. This exam helps confirm how far along the pregnancy is and allows the doctor to check the baby’s development in more detail.
If you’re unsure about how to calculate your gestational age, it’s best to talk to your OB-GYN or midwife. Knowing your gestational age accurately is important for proper prenatal care.
