Pregnancy Week 5

Your Baby's Development This Week

The heart starts beating now, and the four chambers of the heart are functioning. Blood has begun pumping, thus the baby's heart is now beating. The umbilical cord develops, providing a means of nourishment and care for the growing baby. The umbilical cord contains three blood vessels and carries blood between placenta and fetus.

Most organ development is underway, including the lungs and brain which are beginning to form. Arm and leg buds appear, although at this point you may not be able to recognize them as such. However, before long they will be busily kicking and waving about.

The placenta begins to form. The placenta is attached to the inside of the uterus to the baby by the umbilical cord. It is the transfer point between mother and baby's blood supply.

The embryo is 2mm long at end of this week, close to the size of a grain of rice. It's hard to imagine all the minute detailed development that is proceeding in such a small little being.

The precursors of the eyes and ears are forming, although they are primitive forms at present. The eyes are extremely complex organs and take much time to fully develop.

Symptoms You May Feel During Week 5

Particularly those who have given birth before may feel bloated, but might think they are just experiencing PMS bloating. In fact a number of early pregnancy symptoms can be mistaken for signs of an impending period.

Nausea generally starts at week six, but that does not mean you might not begin feeling queasy already. One of the best remedies is to prevent it by eating frequently. An empty stomach quickly becomes a sick stomach in early pregnancy. Keep a stash of saltine crackers on your nightstand and nibble on them as soon as you wake up. Some people swear by peppermint candies, or certain teas.

Breasts sensations are usually the initial symptom of pregnancy. Some women experience extreme breast tenderness, similar to what they might feel during PMS, or even worse while others might feel odd and tingly sensations throughout their breast at intermittent periods.

Frequent urination may be starting already, although don't necessarily expect it. This symptom comes and goes throughout different phases of the pregnancy.

Fatigue is most likely the most problematic symptom a woman will deal with in early pregnancy. It might be mild and not last all day every day, or you might feel completely knocked out all day, every day for several weeks. It's one of the most difficult of the symptoms to cope with, as life rarely just pauses for your fatigue. Look at your calendar and cancel anything too trying or overwhelming that you possibly can. Enlist help from friends and family members. Simplify household chores as much as you can. Remember to let someone else care for the cat's litter box, due to the risk of toxoplasmosis, a blood infection. Also, always wash your hands after touching cats, and keep cats off counters.

While you shouldn't become the pregnant hypochondriac, you should know the symptoms of an ectopic pregnancy, as this is a serious condition and you should respond quickly to any signs of this occurrence. An ectopic pregnancy is when a fertilized egg attaches somewhere besides the uterus, typically in the fallopian tube. Symptoms of an ectopic, or tubal pregnancy include sharp abdominal pain, bleeding, gastrointestinal symptoms, or weakness or fainting. This can be a potentially life threatening event, so seek medical attention immediately when experiencing sharp pains with or without bleeding.

Visit With the Obstetrician

If you haven't made one already, schedule your first prenatal visit with your doctor. If you are interviewing prospective care providers, keep in mind a number of factors when making your decision:

  • How convenient is the location?
  • Where do they have hospital privileges and is your hospital of choice included?
  • Will you see the same provider at each visit or other members of the practice?
  • Do you know others who have used the same provider and had a birth experience that you are hoping for?

You can always switch physicians later if you feel it's just a bad connection, but doing your homework ahead of time can lessen the chance of that happening.

Preparing for Baby

Deciding when and how to tell about your blessed news is something everyone struggles with a bit. Some people chose to wait until the 12 week mark of pregnancy when the risk of miscarriage has plummeted. However, others can't wait to share their joy. Others may decide to let in a small circle of people on their good news. Whenever you decide to share the happy news, go ahead and celebrate this most special life event!

Pregnancy Lifestyle

Dealing with fatigue and nausea is no small task, and if you have other children and or a job, it's even harder to deal with. Try to simplify your life as much as possible. If you usually cook from scratch, consider buying some healthy easy box or frozen meals, keep that pizza delivery number on speed dial.

Are you a compulsive cleaner? Can't stand to skimp on the cleaning schedule? Consider hiring some help on occasion at least during these tough early weeks, when getting off the couch seems like a work out in itself. The easier your schedule and chores, the easier pregnancy will be for you.

Hi, I was supposed to get my period last Thursday but, I never got it. And the week before my period I had tingly nipples, heavy breasts, I feel bloated, have had white creamy mucus and brown spotting on the day of my missed period. And I had red spotting, which I believe is implantation spotting. Could I be pregnant?

We were NOT ttc but had an accident on the 20th August. I was ovulating on 19th. I had niggling and cramping from 21st onwards. From 5 days before period was due I tested with clear blue, all negative. On the first day of my period I tested with a first response and got a big fat positive. I already have 4 children 4,6,8,15. I'm hoping it won't be twins. I know that's more of a possibility as you get older. I'm 38.

Hi. I’ve had everything in the book like light bleeding, feeling tired, feeling sick, and also my boyfriend is having some signs as well. My best friend says I am. My test came out negative, so am I, or is it just a scare?

It could be that you are pregnant, but that the pregnancy hormone hcg is just really low right now. for the most accuracy do a blood test.

I might be pregnant. I had unprotected sex with my bf Jan 1-5. I was on my period which was from Jan 2-6. I still had some bleeding on the 7th. I had headaches on Jan21st, 22nd, and 24th. On Jan 24th, I had cramping with light colored blood. On the 25th, I had some fatigue, and pinkish red spotting mixed with brown. I was cramping also. Then, I started bleeding. That same month I had a second period from Jan 25-29. I still had some bleeding on the 30th and 31st. I had small headaches on the 31st. On Feb 5th, I had pinkish color spotting. I took a HPT and it was negative. On Feb 6th, I had cramping and was spotting a light color with fatigue. On Feb7th and 8th, I still had fatigue, and now a brown colored spotting. Could I be pregnant? Please help.

Hello, id like to start out by saying me an my boyfriend have been TTC. I was supposed to start my period on Dec 3rd, but it never came. According the ovulation test I took, it says I probably conceived on Nov 16th, 2014, but I took a HPT Clearblue test, which came back negative. I'm nervous because I have all the symptoms, but not a positive test result yet. Any suggestions would be great. Thank you, :) and baby dust to all. xoxo

Why do I feel more pain on my left side? I am 5 weeks, and it's my first pregnancy.

I am TTC. My period was expected on the 6th of Dec, but on the 3rd and 4th, I saw some spotting. I thought my periods would have started. After the 4th of Dec, there was nothing. From then on I've been feeling irritated, crampy, and breast tenderness. I had an HPT done on the 7th, which came out negative. On the 10th, I got the blood test done, which again was negative. I am still having all these symptoms along with backaches, and sometimes a pinching pain in my left side lower abdomen. I'm still wondering if I am pregnant!!

jt Dec 17, 2014 11:34:59 AM ET

You probably are. i found out on the 7th of dec, and now i'm 5 weeks. i had done 3 or 4 pregnancy tests between the 22nd and 29th of nov, as i didn't feel right, with tender breasts, tired, and hungry, but all came back negative. i waited until the 7th, and the hpt was positive. i did blood test on the 8th, which was only 262 hcg, so it only just showed up. you might just be too early to show any hcg yet. maybe wait a few more days, and try the hcg. i hadn't even missed a period before doing a pregnancy test, and obviously you never got your period.
