Think you might be pregnant and not sure what’s in store? Here’s a guide to everything you need to know about pregnancy in the first few weeks.

Week 1

At this stage of your journey you are not even pregnant! The full term of your whole pregnancy from conception to delivery is actually around 38 weeks. Doctors calculate from your last menstrual period (LMP) because you may not know when conception occurs — but you do usually know when you had your last period. From the last period to ovulation is 2 weeks. That’s why the entire pregnancy journey is actually calculated from this point.

Week 2

At Week 2 into your pregnancy journey there is still no sign of a baby. This is the week of your cycle where the body gears up for ovulation. The fertile period is based on when you ovulate. The egg can only survive 1 day. If it is not fertilised as it journeys down the fallopian tube, it disintegrates.

Week 3

At conception your baby starts its growth from a single cell to become a fully formed boy or girl almost 9 months later.

Some women are very sensitive and can tell almost at once that they are pregnant. “In fact, the moment they conceive, they can feel that they’ve conceived,” explains Dr Tan Thiam Chye, an obstetrician and gynaecologist. “They realise that they have some symptoms of bloating, a bit of nausea, giddiness, non-specific breast tenderness. Frequent urination may be experienced at this stage too.”

Although most pregnancy symptoms start around Week 6 you may see spotting when the fertilised egg implants (which is usually around a week after conception). “If it’s heavier or if it’s associated with cramps or pain, then you should seek medical attention,” adds Dr Tan.

Week 4

Once you think you are pregnant, make sure you mark down the date of your LMP. This will probably be the most-asked question from medical practitioners during your pregnancy! It helps to pinpoint the start point of your pregnancy and track that your baby’s growth is in line with your due date.

At Week 4 your breasts may feel sore and you are likely to feel an overwhelming sense of tiredness. Your body is going into overdrive to create the right environment for your growing baby.

If you have not already been taking folic acid, you should start taking 800 micrograms of folic acid a day, as it can help to prevent birth defects. Doctors advise taking a folic acid supplement up to Week 12 of pregnancy.

Folic acid naturally occurs in green leafy vegetables such as bok choy and spinach, but since the typical Singapore diet doesn’t tend to focus very heavily on vegetables, taking this supplement is doubly important. Now is the time to start taking care of both yourself and your growing baby!
