So why telephone call these the first two weeks of pregnancy — when you're non fifty-fifty pregnant yet?

In the meantime, while your uterus is pending its tenant, start acting like a skilful landlord. Consider these two weeks of waiting as a final walk-through earlier the infant takes over the keys. Y'all may not exist pregnant yet — at least technically — but it isn't too early on to commencement acting like you are.

Your infant is a microscopic ball of cells this week, ane-fifth the size of the period at the end of this judgement. Only y'all've got yourself a infant-in-the-making, ready to brainstorm the incredible journey that will cease in your arms.
Three weeks into your pregnancy — and conception has finally occurred. The magic moment when sperm and egg fuse (otherwise known every bit fertilization) results in a zygote, a single-jail cell organism made up of genetic material from both you and your partner. Peel away that technical jargon and you've got yourself a baby-in-the-making, ready to begin the incredible journey that will end in your arms.
So congratulations are in order. At present, will this single cell miraculously transform into a girl or a boy? Though it volition be months before you'll be able to notice out for certain (if you choose to), that remarkable determination has already been fabricated. Prepare for a crash course in biology? The fertilized egg (aka your baby) contains 46 chromosomes — 23 from y'all, 23 from Dad. The mother (yep, that's you!) always provides an X chromosome. The father tin can provide an X or Y chromosome. If the sperm that fertilizes your egg carries an X chromosome, the Xx zygote will be a girl. If the sperm is Y-begetting, then your XY zygote will be a boy.
The single jail cell doesn't stay unmarried for long: Within hours, the cell divides, then each cell divides once again. Within days, you're walking around with a microscopic ball of cells, ane-fifth the size of the flow at the terminate of this sentence. Tiny? Certainly. But don't underestimate its potential.

Half (now chosen the embryo) will become your son or daughter while the other half becomes the placenta — the lifeline that channels nutrients to your baby and carries waste matter away.

Right now, your baby'south heart is fabricated up of two tiny channels called heart tubes — and they're already hard at work, beating to their ain drummer (it will be weeks before those beats go coordinated). When those tubes fuse together, your babe will have a fully functioning heart (though information technology most certainly already has its grip on yours). Also in the works this week are several other organs, including the neural tube (the precursor to your baby'southward encephalon and spinal cord), which hasn't yet sealed, but by next calendar week, that admissible policy is over.
