9 Week Pregnancy in Months
Your doctor and midwife will usually measure your pregnancy in weeks, but perhaps you’re curious about how many months is equal to 9 weeks. There are various ways of grouping the 40 weeks of pregnancy into months; however, at 9 weeks pregnant, you’re likely in your third month of pregnancy, even if you haven’t noticed any belly bump or symptoms!
Between weeks 8 to 14, you’ll be offered a dating scan which will estimate your baby’s due date. If at 9 weeks pregnant, you haven’t yet found out your due date via ultrasound, you will in the next few weeks. Until then, you can use our Due Date Calculator.

Your Body at 9 Weeks Pregnant
Symptoms at 9 weeks pregnant might be very intense because pregnancy hormones are increasing, and hCG levels have doubled in amount every two to three days since the start of your pregnancy and reach its peak around week 9. This means you might be feeling intense nausea, very moody, extremely tired, and just a little tender all-round.
It might help to keep in mind that hCG plays a very important role in keeping your pregnancy on track and your foetus happily snug in the uterus.
Another plus is that in about a month or so, you’ll be in the second trimester and probably feeling much better!
Although, you might be dealing with lots of pregnancy symptoms right now, this is also a great time to talk to your midwife about exercising during your pregnancy.
If you're already active, you may need to make some adjustments to your fitness routine, but you can probably keep up with what you currently do for as long as it feels OK and as long as your midwife gives you the all-clear. If you haven't been as active, choose a safe activity to help get you moving, such as walking, prenatal yoga, swimming and water aerobics – all excellent choices as they're gentle on your joints.
Moderate exercise will help you develop the strength and stamina you'll need during labour and delivery. Try not to exhaust yourself, drink plenty of water and follow the guidelines suggested by your midwife or the exercise instructor. If you do a group class, the instructor may suggest adaptations suited for pregnancy.

What Size Is a Pregnant Belly at 9 Weeks?
At 9 weeks, your pregnancy bump probably won’t be showing just yet, especially if this is your first pregnancy. Remember, your baby is only the size of a cherry at 9 weeks! It’s common for that bump to start showing around 12 weeks pregnant. If this is your second pregnancy, your bump may show earlier than 12 weeks due to the changes that occurred to your body in your first pregnancy. You may also have started to show if you’re 9 weeks pregnant with twins.

Your measurements will be taken. And, the rest of your antenatal care will be explained.
