If you already have a belly when you become pregnant, you may wonder if you will "pop" at some point in the same way that more slender expectant women do—in other words, reach a point when you'll suddenly look pregnant rather than overweight.
Whether this is a real concern of yours—because you want it to be clear you're pregnant, for example—or you're simply curious, the answer is: it's hard to say.
The ways in which women carry their pregnancies are as varied as the babies they have on board. In other words, everyone is different and unless you've been pregnant before only time will tell how your body will change as your condition progresses.
One thing that is for sure is that you're not alone: Women of every size often wonder when their pregnancy will show. What's more, there are normal-weight women who wind up looking more as if they've put on extra pounds than that they're pregnant.
While the appearance of a baby bump certainly is a legitimate thing to wonder about, if you have a plus-size pregnancy you'll want to keep some other issues in mind as well, so that you and your baby-to-be can enjoy your nine-month journey together safely and healthfully.
Your Changing Shape During Pregnancy
Regardless of how your belly is shaped when you become pregnant, as your baby grows your body will definitely undergo changes.
During the second trimester of pregnancy, the uterus first begins to expand beyond the pelvis, and so most women begin to look obviously pregnant somewhere between weeks 12 and 16. By the middle of the second trimester, maternity clothes may be in order to accommodate a morphing middle.
If you have a prominent layer of fat blanketing your abdominal area, it may take longer for your baby bump to become obvious or you may experience a different kind of change in the appearance of your belly. Maybe it won't become bigger, but the shape may shift a bit—you might look rounder, for example.
The question really comes to how to let others know that you're pregnant if you're ready to for the big reveal before you're really showing. Dressing the part is one way to go: Start wearing maternity clothes. Choose styles that really emphasize your pregnant belly to highlight your condition.
Weight Gain Guidelines
What you should not do is attempt to control the appearance of your baby bump by attempting to gain more or less weight than your doctor or midwife advises.
If your body mass index (BMI) is between 25 and 29.9 before pregnancy, you are considered overweight. Doctors advise limiting weight gain to no more than 15 pounds to 25 pounds. If your pre-pregnancy BMI is 30 or greater, you are considered obese, and doctors advise limiting weight gain to between 11 pounds and 20 pounds. If you're carrying twins, you can double those numbers.
Pre-Pregnancy Weight Loss
If you aren't yet pregnant, it can be a good idea to try to lose weight before you try to conceive if you're overweight or obese. Both conditions bring unique potential problems to pregnancy including an increased risk of pregnancy loss, birth defects, a larger-than-normal baby, and difficulty monitoring fetal development with ultrasound.
Developing Healthy Habits
Pregnancy is a great time to initiate healthy habits that you can carry on beyond the birth of your baby to help you lose the baby weight (and perhaps even more).
With the guidance of your healthcare provider, focus on eating a balanced diet high in nutrient-dense whole grains, fresh fruits and vegetables, lean protein, and low-fat dairy.
At the same time, rid your diet of added sugars, saturated fats, and low-nutrition foods that don't benefit you or your baby. And count your calories: You don't need any extra calories in the first trimester, but you do need 340 more calories per day in the second trimester and 450 extra calories in the third trimester.
If you don't already exercise now would be a good time to start. Talk to your doctor first to get guidance about how to start an exercise program and how to progress safely.
Walking often is recommended for pregnant women of any size. And besides, you'll need to be up to pushing a stroller before you know it, so you might as well start building up the strength and stamina now.
