The first trimester is the probably the most exciting of your entire pregnancy – everything is so new and overwhelming. During the next 12 weeks, your baby will turn from a fertilised egg into a 3-inch human who is responsive to sounds.

Your plan for your first trimester

To start with, give up smoking and alcohol and cut back on caffeine. Start taking folic acid supplements – if you aren’t already taking them. Remember from this point onwards to check any medicines to see if they are suitable for pregnant women.

Rethink your diet if it’s not quite healthy. Research foods that are best for you and your baby and which you could avoid. Some will help you to fight morning sickness and get an energy boost, others will help your baby to stay healthy. Have sex if you feel like it – it’s harmless, and has its benefits.

Take time to plan out your pregnancy and life with a newborn, especially the financial side of it. Find out about your company’s maternity leave policy, and start saving for those big purchases like pushchairs and nursery furniture.

You will need to go for your first antenatal appointment and pick an antenatal care option that suits you. By the end of your first trimester you will go for your first ultrasound and get to see your baby for the first time – find out more about your 12-week scan here.

Hormone rollercoaster

If this is your first pregnancy, there are a few surprises that await you. Tender breasts? Odd food cravings? Morning sickness? You may add heartburn, constipation and extreme fatigue to top up the list of typical pregnancy symptoms caused by hormones. But worry not – there are tips and tricks to help you deal with each one of them.

Risks to be aware of

Most miscarriages happen in the first trimester. There are some risk factors that include obesity, smoking during pregnancy, use of drugs and overuse of alcohol and caffeine.

If you notice any of the following symptoms, they may indicate an early miscarriage or ectopic pregnancy. Call your GP or midwife and get an ultrasound check to make sure everything is fine.

  • Vaginal bleeding (light spotting is perfectly normal)
  • High temperature
  • Severe abdominal (tummy) ache
  • Diarrhoea and vomiting
  • Strong dizziness
  • Visual disturbances
