The early symptoms of pregnancy and the first stages of fetal development.

Your Baby

Pregnancy is calculated from the first day of your last period.  Even though a woman does not ovulate until about two weeks after the her period’s onset, the days before conception actually occurs are still considered as part of your pregnancy time count.

Implantation occurs 10-14 days after conception.  Some slight spotting or bleeding is common and is caused by the fertilized egg burrowing inside the lining of the uterus.

The neural tube forms.  This will later develop into the nervous system, forming the brain, spine, skin and hair.  The heart begins to develop at this early stage.



Changes in your Body

Early symptoms of pregnancy are similar to those of the onset of your period.  You may feel fatigue and a soreness of the breasts.  It is important to remember that pregnancy symptoms vary in different women and from pregnancy to pregnancy.  You may find yourself experiencing certain symptoms earlier or later than average.

If you suspect you are pregnant or are considering becoming pregnant, be sure to take a supplement of Folic Acid.  Make sure your body gets enough Folic Acid is very important to ensure a healthy formation of the baby’s neural tube and can prevent spinal bifida, a defect in the spinal chord.  Avoid x-rays, smoking (even second hand smoke), alcohol, and limit your intake of caffeine.  Overheating may damage the fetus, so avoid very hot baths, saunas and hot tubs.

What to do...
written by Kristin, February 04, 2009
Hi I'm 22 engaged and newly pregnant. I'm exstatic! I honestly couldn't be happier! However my mother is incredibly upset about the engagement so I have yet to tell her about the baby. I'm not quite sure how to broach the subject. I know she's going to be even more upset and tell me I'm wasting my life... I don't feel that way, but it's upsetting that she can't accept the fact that I'm happy. Any one have any advice??
Dilemma
written by Sandra Bostick, March 19, 2009
Hi Everyone,

I just found out that i'm pregnanct. According to the pre-natel nurse i'm about 5 weeks. I'm nervous because I went to my Mom's birthday on Feb. 28th and had one shot of tequila as a toast for her birthday. At that time I had no clue that I was pregnant and right now i'm still not sure that I was at that time. The 5 weeks is based on the first day of my last period ... What do I do? Is there any chance that I wasn't pregnant on that day? Can the doctor tell you the day you conceived?

Kirsten, I say wait a week and then take a pregnancy test. And, it could be in your head, that's happened to me, before. Good luck either way!

Hello! I had my Mirena IUD taken out about a month ago so that me and my husband could have a baby together. We have pretty much been trying since then. A couple days ago my stomach started feeling...I guess you could say full all the time, my boobs are now starting to feel real tender and I've been really tired lately. I have a 4 year old daughter already, but I don't ever remember my stomach feeling this way. Any advice on what to make of my situation?
Am i Or no?

Im 22 and i have just found out im pregnant. im not happy, it is a total shock and i still havent got my head around it. abortion is not something i believe in, not for religious reasons jus because it is your responsibility. Me and my now ex split up because he wanted me 2 have an abortion and i refused. You do not want to do something that you will regret forever. bSurely everyone that is having problems has got friends they can talk to for support? I have yet to tell my family but my close friends are there to support me no matter what. Im hoping I can do this by myself its just all a bit scarey atm!!xx
