Pregnancy week 3

Pregnancy guide: week 3 of being pregnant - Your fertilised egg is travelling doen your fallopian tube towards your uterus..

You

Seven days after implantation, chemical signals are sent to stop your period. You may experience some spotting when your egg implants itself into the uterus wall.

Your baby

Your fertilised egg is travelling down your fallopian tube towards your uterus, dividing and multiplying into a cluster of cells (known as a blastocyst). Your partner's sperm determines whether your baby is going to be a boy or a girl.

By the end of the week your fertilised egg will have embedded itself into the uterus wall and will begin to grow. At the same time the placenta (afterbirth) begins to develop. This, via the umbilical cord will be your baby's link with you as he or she develops.

The cells develop into a flat disc, no bigger than the size of a pinhead that contains three layers. The innermost layer will become your baby's organs, urinary and digestive systems. The middle layer will form your baby's bones, muscle, heart and blood vessels. The outer layer will produce your baby's brain, backbone, nervous system, skin, eyes and ears. As early as the second week a dark mark appears on your embryo's back, marking the start of the spinal cord.

do all mums-to-be suffer from morning sickness?
by justme1970	5th Nov 2010, 5:02pm

Hi!! i was told by doctors im just after 4 weeks, but i worked it out that i think im only around 3 weeks ( if i calculate from when i would have ovulated ) I found out i was pregnant on Monday 10th October, and on the Tuesday I had cramping all day which worried me, i also had a bit of blood (about 2 drops). I went to the hospital and they gave me an Ultrasound which showed no Sac or anything, but it did show I had a thick lining in my womb and everything else looked healthy, she advised me it was too early to see anything anyway and not to worry ( she told me i was just after 4 weeks) . Anyway today cramping has stopped going constant, i can still feel it every hour or so, and when i went to toilet i noticed one drop of Browish blood. I have to go back to hopsital on Thursday and get my blood taken again to see if the hormones are doubling, but im just so worried that ive had a miscarriage, as its fairly common and it really sounds like it. Either that or its implantation bleeding. Anyone experienced the same as me or have any advise?? this is my first pregnancy and im terrified of anything going wrong :(

Hi everybody, congratulations on your pregnancies, hope they are all joyous occasions. We should not forget that some people get pregnant accidentally/unexpectedly and are consequently scared silly and unprepared. My advice is to find a friend, family, and/or medical professional who you can confide in and get the answers to your questions and fears. If you are unable to do this, go and buy a book or two. There are all sorts available for those who need the facts, and also ones that help you deal with your particular emotions if you are young or going to a single parent etc. or have a special medical condition. Good luck and try to relax!
We've just tried for our second baby, so could be about 3 weeks along if successful. I conceived first month of trying last time round, was just wondering if anybody knows if I am likely to conceive as quickly, 14 months between first baby and second attempt, had an emergency c-section, otherwise no complications. Periods arrived two months before I stopped breast-feeding at 11 months, so periods started 9 months after giving birth and have been regular and normal since. I do have endometriosis, so was very lucky to conceive so quickly, expected it to take at least 6months - 2 years! Fingers crossed.

3 weeks pregnant, scared, whats gonna be happening to me at this stage?
by racahelc1aire	14th Dec 2009, 9:25am

I'm sure your baby is fine, it really is only the size of a pin head as it has only been developing for a week, as you are not actually pregnant for the first 2 weeks. Don't panic as it will only stress you out and the first 12 weeks are vital so try and relax and not worry

Hi All,
Last week I check to my doctor, because I was 5 days late for my period, and I do a pregnancy test and the result is Positive. after asking the date of my last period, the doctor predict that my baby was about 3 weeks. But when doing scanning Inside, the doctor Didn't see anything.. I was SO WORRY.. The doctor Affraid that I might have ectopic pregnancy, and told me to comeback 2 more weeks, to do scanning again... and to see what really happen.
Now, I wait in worry and affraid that the worse can Happen. I'm so confuse, what could happen??
Is it possible that the doctor just could not see yet my baby, because its just 3 weeks old? Or I'm having an ectopic pregnancy? Can I have more Explanation about this please?? =(

I came of my pill last aug 2008, my periods have been every 5 weeks apart from last month they were 29 days later. Im due my period on sunday going by a 28 day cycle. But monday night before i went to bed i noticed a little pink in my discharge, but did'nt think anything of it, and i had sex with my hubby and when he pulled out, he noticed a pinkie colour blood on him, when i went to the toilet i noticed it was also on the tissue. so i wore a pad thinking my period may of started early. But nothing else has happened. I have been having sex every 2-4 days since my last period hopeing to get lucky this month, i worked out if i am preg that i would be about 3 weeks. So i was wondering if it could of been an implant bleed. I bought 2 preg test, but i want to wait till sunday to see if my period comes, as i dont want to get my hopes up!! Has anyone else experienced?? If anyone could help, it would be much appreciated!!

Hi
My fiance and I decided to try for a baby just before Christmas (I already have 2 teenage boys). I did a digital test at the weekend which was positive and I am 3 weeks pregnant. Naively we did not anticipate conceiving this quickly but can't tell you all how thrilled and excited we both are. We are still at the stage where we can't believe it is happening. Want to tell the world but can't, it's the biggest and hardest secret to keep. I'm feeling sick all day everyday, apart from when I am eating! Breasts feel swollen/tingly and my appetite has increased. This is so special!!

Im just in the middle of the second week and im starting to feel strange - i don't feel like eating and just don't feel right - can not explain what I mean - but has anyone else felt like this? I have been pregnant before, however I don't remember feeling like this - is it just me wanting this so much or is it a sign?
by Fishy	21st May 2008, 8:47am

I've just done an IVF cycle so I know my two embryos are in me. I am getting fluttering feelings in my tummy & just hope this is a sign that the blastocysts are implanting.
