El embrión tiene 7 semanas de edad. Duplicó su tamaño, ya mide entre 10 y 13 mm. y se lo puede ver y escuchar mediante una ecografía.
La cabeza es enorme en relación al resto del cuerpo. El corazón late muy rápido y ya tiene cuatro cavidades. Los bronquios comienzan a desarrollarse en los pulmones. Las manos y pies se asemejan a aletas.
¿Qué me sucede esta semana?:En tu cuerpo, el abdomen todavía no se hace notar, pero ya puedes haber aumentado algo de peso.
Ahora sí o sí, tienes que ponerte en contacto con tu ginecólogo, han pasado tres semanas desde la fecha que tendrías que haber menstruado. Es evidente que algo esta pasando... ¿Cómo todavía no hiciste un test de embarazo?.
Recuerda de evitar la ingesta de alcohol, tabaco, drogas, medicamentos y reducir la toma de café al mínimo, ya que altas dosis de cafeína están asociadas a interrupciones de embarazo durante el primer trimestre. También debes evitar exponerte a radiaciones como los rayos X (radiografías) y sustancias químicas peligrosas.
How your baby's growing:
The big news this week: Hands and feet are emerging from developing arms and legs — although they look more like paddles at this point than the tiny, pudgy extremities you're daydreaming about holding and tickling. Technically, your baby is still considered an embryo and has something of a small tail, which is an extension of her tailbone. The tail will disappear within a few weeks, but that's the only thing getting smaller. Your baby has doubled in size since last week and now measures half an inch long, about the size of a blueberry.
If you could see inside your womb, you'd spot eyelid folds partially covering her peepers, which already have some color, as well as the tip of her nose and tiny veins beneath parchment-thin skin. Both hemispheres of your baby's brain are growing, and her liver is churning out red blood cells until her bone marrow forms and takes over this role. She also has an appendix and a pancreas, which will eventually produce the hormone insulin to aid in digestion. A loop in your baby's growing intestines is bulging into her umbilical cord, which now has distinct blood vessels to carry oxygen and nutrients to and from her tiny body.
How your life's changing:
Your uterus has doubled in size in the past five weeks, and eating may feel like a chore — or worse — thanks to morning sickness, which by now may be in full swing. (If you're feeling fine, don't worry — you're lucky!)
You may need to pee more than usual, too, thanks to your increasing blood volume and the extra fluid being processed through your kidneys. (By now, you already have about 10 percent more blood than you did before you were pregnant. And by the end of your pregnancy, you'll have 40 to 45 percent more blood running through your veins to meet the demands of your full-term baby.) As your uterus grows, pressure on your bladder will send you to the bathroom as well.
About half of the women who feel nauseated during the first trimester will find complete relief by about 14 weeks. For most of the rest, it'll take another month or so for the queasiness to ease up. It's unlikely, though, that the need to pee more than usual will ease up. In fact, research shows that both the frequency and volume of urine tends to increase over the course of pregnancy.
