Pregnancy Checklistcheck your pregnancy week by week

20 January 2018
You are on the 4th week of your pregnancy now!

At week 4 (this OB term, which corresponds to the second week of embryological development) the size of the embryo is about  0.04 in(like a grain of sand) and this week, the embryo becomes a fetus. The embryo consists of three layers of cells, which as they progress, they go different ways.
Outer layers of cells, or ectoderm, will form the skin, hair, nails, nipples, and tooth enamel together with the lenses of the eyes, the nervous system, and the brain. The middle layer, or mesoderm, will become the skeleton and muscles, the heart and blood vessels, together with the reproductive organs. And finally, the innermost layers of cells, the endometrium, gives rise to the respiratory and digestive systems including the liver, pancreas, stomach, and bowel together with the urinary tract and bladder. Once a cell has been directed or programmed to have a specific function, it cannot change to become another type of cell.

  • I got my first big indication of pregnancy: my period is late!
  • Today’s the big day! I took a pregnancy test and got a Big Fat Positive. I’m officially pregnant!
  • I called my obstetrician or midwife, and my first prenatal visit is on the calendar.
  • I’ve got my list of questions for my first prenatal visit. I wrote down any special concerns or issues I want to discuss with my doctor.
  • I’m keeping out of hot water. No hot tubs or saunas, and I’m setting the water to body temperature for baths and showers.
  • I’m stocking up on foods that can help with morning sickness or nausea. My pantry is full of bland carbs like crackers and dry cereals.
  • I’ve pregnancy-proofed my medicine cabinet! I separated medicines that are safe during pregnancy from those that aren’t, and I’ve printed out a handy list so I don’t have to look medicines up when I’m feeling sick.
