Pregnancy Week by Week

Get a window on what’s happening in your pregnancy, week by week. From week four to week 42, your baby is experiencing a miraculous transformation from a clump of cells to a fully formed (and totally cute) newborn. Just imagine, as early as five weeks, your baby is already starting to form major organs (heart, stomach, liver, and kidneys) and systems (digestive, circulatory, nervous). By eight weeks, your raspberry-sized womb-mate is moving her arms and legs. At the beginning of your second trimester (week 14), your wee one is sucking his thumb. By week 28, the first week of the third trimester, baby (now as big as an eggplant) is prepping for breathing, developing his eyesight and packing on pounds in anticipation of life outside the womb. Each week is a new miracle. Less miraculous is how a mom-to-be may feel. Pregnancy Week-by-Week charts your baby’s development but also lets mom know what she might be feeling during each week of her pregnancy. Pregnancy week by Week includes everything mom needs to know to feel a sense of control over her pregnancy. Each week offers a complete guide to what you might feel, your must-do’s, your nice-to do’s, and answers and advice on everything pregnancy-related. Plus each week’s guide offers tips on maintaining a healthy and comfortable pregnancy from strategies on coping with pregnancy symptoms (morning sickness anyone?) to ideas for healthy eating, and pointers on talking to your OB. Let us guide you along your pregnancy, week by week.

Q&A: Losing weight during pregnancy?

I just found out I’m pregnant, and I’m actually losing weight. Is this normal? Should I be worried?

Re: I just found out I’m pregnant, and I’m actually losing weight. Is this normal? Should I be worried?

The Bump Expert

It certainly seems strange to lose weight when you’re creating a whole new person, but it’s probably nothing to fret about. Morning sickness and the accompanying loss of appetite can cause you to shed a few pounds in the first trimester. Don't worry -- you'll more than make up for this loss in the upcoming months. And remember, most women only gain between two and five pounds in the first trimester.

Still, you can (and should) take action to ensure you and baby get the nutrients you need. Prenatal vitamins are the way to go,though you might want to try one with a low dose of iron (the mineral can actually make nausea worse). And, try to eat whenever you can stand it.An empty stomach can actually trigger nausea, as can low blood sugar,so eat before you are hungry and always keep snacks nearby. Getting extra sleep and cutting down the stress will also work wonders for your appetite.

For an alternative remedy, try ginger. (Ginger ale, ginger candies, ginger beef with snow peas…) It has a long history of making tummies feel better. Or slip on an acupressure band, found at most drugstores.The bands -- meant to ward off seasickness --help many a mom fight the queasies. If you continue to lose weight or simply can’t keep anything down, talk with your doctor.

Q&A: Losing weight during pregnancy?

For my first pregnancy I lost 20 lbs in my first trimester! I was about 163 before, and dropped to 143...I ended up gaining all and then some back throughout the pregnancy (178 at 38weeks). I think the biggest reason for my weight loss was cutting out ALL pop, fast food, drinking close to 3 liters of water a day, my eating habits (small meals and snacks all day vs one big meal). Plus I worked at a daycare, so I was chasing 8 3-year olds all day long, and in the beginning my appetite was almost non-existent due to nausea. (I wasn't trying to loose the weight it just happened..wish it worked like that all the time!) I am now 6 or 7 weeks into my 2nd pregnancy and feel WAY more sick than i did with the 1st..scale is just going up. The biggest reason I think is because I feel so sick(week 4 was the worst) , i resort to my "comfort foods" I know I can get and keep down. As my sickness subsides (its getting better every week) I am starting to eat the healthier foods and not so many carbs (potato, noodles bland foods I could keep down) ..Ive also started to walk 3- 4.5 miles a day ( I am a stay at home mom now) in the last week or so I've dropped 3pounds. Again I am not trying to loose weight, but I am working to be more matter what the scale says..if you are doing your best to be healthy your baby is most likely getting what it needs. Hope this helps...its amazing how different your 2nd pregnancy can be!

Q&A: Losing weight during pregnancy?

During my first pregnancy, i think i lost around 13 lbs over the first 1/2 of the pregnancy. Then gained that back plus another 13. I'm overweight/obese so i figured it was just my body was working efficiently for once. plus all the calories burned making a human probably helped too. This time around im 8 weeks so far and I've lost a couple pounds.

Q&A: Losing weight during pregnancy?

With my first pregnancy I think I lost 2-3 pounds. I gained 20 through the rest of it. I have been trying to lose the last 10 pounds for the past 3 years (my DS is 3),I get pregnant 2nd time around and I have lost almost 10 lbs since week 6 ( I am 8 weeks). I am trying to eat stuff and I found Shogun's salad with ginger is great, but no matter what I am still losing. Am I doing something wrong?

Q&A: Losing weight during pregnancy?

This is my first pregnancy. I lost 6 lbs from week 6-week 7 because I could not keep foods down. I could barely even shower because the smell of soaps and chemicals would make me gag. I went to the hospital once for IV fluids but then received a prescription to help with the nausea. If you are losing a lot of weight or cannot eat/drink for 12+ hours make sure to call your doctor. Try popsicles, animal crackers or cheerios.
