What you need in the first trimester

The first trimester is often the most tiring, even though nothing shows on the outside. Your body is working flat out. Here is what really helps in these weeks, and what can wait.

What is happening

The first trimester lasts until week 12 of pregnancy.1 Tiredness, nausea, tender breasts and needing to wee more often are typical; you will find a list of early symptoms in the article Early signs of pregnancy.4

Supplements

The NHS recommends two supplements in pregnancy: folic acid and vitamin D. A varied diet usually provides the other vitamins and minerals.3

SupplementNHS recommendation
Folic acid400 micrograms a day, ideally from 3 months before conception or as soon as you know you are pregnant, until week 12; some women need a higher dose2
Vitamin Da supplement throughout pregnancy3

Discuss doses and specific products with your gynaecologist, especially if you take other medicines or have a long-term condition. Slovak recommendations may differ in the details from British ones.

Tiredness and nausea

  • Eat smaller portions more often; some women find it helps to eat something small before getting up.
  • Sip drinks little and often through the day.
  • Rest when you can. Tiredness in the first trimester is not laziness.
  • If you cannot keep fluids down, or you are passing very little or very dark urine, get in touch with your doctor.

Your first visits to the gynaecologist

In Slovakia, pregnancy is monitored at the antenatal clinic (tehotenská poradňa) run by your gynaecologist. Have ready:

  • the date of the first day of your last period,
  • a list of medicines and supplements,
  • the questions on your mind (write them down beforehand),
  • information about conditions that run in the family.

You will be given a pregnancy record card (preukaz pre tehotné, often called the tehotenská knižka). Carry it with you; you will also need it at the maternity hospital.

Clothes in the first trimester

The bump usually does not show yet, but your waistband and bra may feel tight. A soft bra without pressure and trousers with a stretchy waistband are enough. There is no need to rush into buying maternity clothes yet. More in the article When to start wearing maternity clothes.

What can wait

  • the baby kit,
  • stocking up on maternity clothes,
  • big purchases (pram, cot).

There is time for all of that in the second trimester. The first trimester is for resting and getting used to things.
