Baby Bump Week by Week: Trimester 1 Month 1

Baby Bump Week by Week: Trimester 1 Month 1

BODY: MONTH 1 ( WEEKS 0-4)

 

WEEKS 1 &2: Your body is going hormone haywire! You should be ovulating and ideally fertilizing.

  • Follicle Stimulating Hormone (FSH), this hormone triggers the follicles to mature. Each follicle has an egg, and ultimately the most dominant one will be the chosen one for potential ovulation.
  • Once the follicles mature, estrogen comes in and has two important jobs for ovulation:

1.) Thickening of the uterus wall, creating a sound environment for an embryo

2.)  High concentrations of estrogen will stimulate its fellow friend Luteinizing Hormone (LH) to be produced. This helps push the mature follicle through the ovarian wall to then start ovulation.

Once inside, your eager egg will meet its beloved sperm; your egg becomes a baby in the making.

 

WEEK 3: Production of progesterone and estrogen are increased, enough to nourish and support your future baby until the placenta takes over in about 10 weeks! About a week after fertilization, the soon to be embryo is nestled into your uterine lining while the placenta takes shape.

 

WEEK 4:  The newly developed placenta begins making a hormone called human chorionic gonadotropin (hCG). This increase in hCG during the first trimester tells your ovaries to stop producing eggs and triggers more estrogen and progesterone. This supports the growth of placenta by keeping the lining of the uterus from shedding.

This is when your body truly transforms and internally you feel all out of whack. Some people may feel:

  • cramping, Ÿ mood swings
  • tender breasts Ÿ bloating

Only 30% of woman have “implantation bleeding” and this is nothing to worry about. It will show up a light pink, light red or light brown hue and typically will occur a few days before your next period.

 

BABY: MONTH 1( WEEKS 0-4)

Just because there is no “baby” inside yet or even an embryo, that doesn’t mean that the race has not begun! Currently there is an eager egg awaiting numerous sperms. During week 1 and the following week (which correlates to the week of your period and the last day of your period), your body is gearing up for ovulation. Your uterus is now getting ready for the arrival of a fertilized egg (sperm and egg match)

WEEK 1:  This week you ovulated and you have finally conceived! Your soon to be cell is starting its journey to be a bouncing boy or girl!  The now called zygote, will travel together on the fallopian tube “train” to then implant and live in your uterus for the next 40 weeks.

WEEK 2: Implantation has occurred and you officially have a bun in the oven. At this point the zygote splits, and half becomes your embryo (future child) while the other half forms your placenta.

Currently your baby is extremely tiny- no longer than one millimeter and no bigger then a poppy seed. During this week your baby is setting up house inside with the amniotic fluid forming around it.

Your baby has three distinctive layers of cells which all refer to specialized parts of your baby’s body.

  • Inner layer: digestive tract, liver and lungs
  • Middle Layer: heart, sex organs, bones, kidneys and muscles
  • Outer Layer: nervous system, hair, skin and eyes
