My Pregnancy Week 5

Pregnancy Week 5

Even though this may be the first week a home pregnancy test confirms your pregnancy, it is incredible how many changes your little one has already gone through. By week five, the embryo, now securely nestled in your uterine wall, will begin dividing into three layers of cells: the ectoderm, the mesoderm, and the endoderm.

Ectoderm
The top layer of cells is called the ectoderm. The neural tube, which will eventually form the spinal cord and the brain, will begin to develop this week. Skin, hair, nails, and sweat glands will all develop from this layer.

Mesoderm
The most impressive changes this week take place in the middle layer, called the mesoderm. Though your baby is only about the size of a grain of rice, the heart has divided into chambers and will begin pumping blood this week! Muscles, cartilage, bone, placenta, and the umbilical cord will also all develop from this layer.

Endoderm
Your baby’s lungs, intestines, thyroid, and pancreas will eventually develop from the endoderm.

    This is my first baby! I am married to my babies father. I am 21, and he is 25. I am really hoping for a boy, ugh! but either way I am so excited and ready for this journey. I am so nervous and scared but I know everything will be okay! I quit smoking a week ago (thank gosh) and now I’m just preparing myself and getting ready I just wanna do everything right and the correct way! Blah, any not first time moms have advice for a first time mommy! P.S. I have the worst fear of giving birth, the pain freaks me out, how do I get over that?

      Well first off, congratulations! I am a mommy of 3, and 1 on the way (last one for me) and every pregnancy was just as exciting as the firat. It is wonderful that you stopped smoking. Seems you already are on the right path. I wouldnt stress too much about not knowing what to do, jt really does come naturally. And any questions y I’ll i have, there are plenty or places to find answers to them. As for the labour pain, well, there is medicine for that. It does hurt, but its a different kind of pain to me. The contractions are a pain in the butt. But breathing thru them and not getting all worked up really does help. As for the baby coming out, the pushing to me is exciting because you know your baby is on its way. ( and it feels like you are trying to take the biggest b.m.) the “ring of fire” as people call it is when the head is crowning. But it dnt last too long and isnt really all too bad. All in all, everybody experiences it differently, but if you go in with a clear mind and dont panic or over think everything, it wnt be as horrible as you are expecting. And again, they do have mesicine to help wase it. Good luck! And plz keep us posted

    Hi, I’m Sara. I’m 33 and this is my second pregnancy. I have a nine year-old daughter so I’m pretty much starting over. I’m five weeks now, I took a test the day my period was due because I just had a “feeling” and my test was positive. I knew for a whole week before I told my boyfriend because he was out of town and I wanted to tell him in person. Since he found out, he has been really distant and quiet. I suddenly feel like a lepper and feel very alone. I’m sure he’s still processing the information but it would be nice if he asked me how I was or even kissed me. It’s very depressing.

    • Avatar of jessica jessica says:

      I know the feeling about starting over. I’m 27, this is my 2nd pregnancy, and I also have a 9 year old daughter. I was the same way about having the ‘feeling’ of being pregnant only after 2 days of missing my period. sorry to hear about your boyfriend.. but u are probably right, he is probably trying to process it all. it’s a lot to take in. i am no longer with my boyfriend, so I’m doing this all on my own, with the help of my mom. just trying to stay positive is all u can really do.

    Hi i’m Elisa, i’m 18 and this is my first pregnancy. I’m around 5 weeks pregnant. I didn’t know I was pregnant until today! I’m so excited but scared because sad to say my menstruation isn’t normal every month, I never expected I would be pregnant and because of that I have been drinking alcohol and taking in random over the counter medication for colds that have been coming and going lately. I just want to know if this would affect the development of my baby at this early of a stage. Does anybody have any advice?

    • Avatar of Megan KlayEditor Megan Klay says:

      Hi Elisa – Congratulations on your pregnancy! This happens to many women whose babies turn out perfectly fine. Don’t stress yourself; as this isn’t good for baby either! When you do go in for your first appointment with your OB, discuss your concerns with them so they’re aware. Best wishes for a happy and healthy remainder of your pregnancy!

    I’m 36 and pretty much shock

  7. Avatar of Louise Louise says:

    I’m 36 and I am going thru a lot more than ever. I need help with food in my local town of Santa Maria California. I live in uninhabitable house and no one in my town will help me. My husband was in a traumatic accident that left him with a broken leg. A paramedic vehicle ran him over. Can anyone help.

    • Avatar of Megan KlayEditor Megan Klay says:

      Hi Louise – There should be services in your town or state which can help. Also, is your husband receiving any financial support from the ambulance company who ran him over? Best wishes to you and your family.

    This is my second baby. I have a daughter who will be 11 on October 8th. I was told I wouldn’t even be able to have another child. So this is a miracle in so many ways. The first time was pretty stressful and I am looking forward to getting to do it all over again. My daughter is so happy to be having a brother or sister.

  22. Avatar of Latoya Latoya says:

    This is my second child. I call this one my miracle baby. My daughter Kayla was 14 when she passed November of 2011. So to find out me and my new husband are pregnant is a new beginning spiritually and mentally. When it comes time to celebrate my daughters passing.. i will also be celebrating the new life growing inside of me. Im thankful

  23. Avatar of baby baby says:

    hey dawn, im 5 weeks and 3 days so i guess we can compare notes!!! dont be scared just relax and first pick a doctor and the doctor should be with a hospital.

  24. Avatar of Carissa Carissa says:

    I would first and foremost find two hospital options you are comfortable with. Then find an OBGYN who serves at one of those hospitals. Remember that this is most important: you MUST be comfortable with this doctor. Otherwise, you will not have a good hospital experience. Besides, you will be seeing the OBGYN regularly, so why not like them? I honestly would choose the hospital closer to home; you do not want to be driving an hour when after you finally get to take your baby home!
