Can’t Sleep in Pregnancy? Causes by Trimester and Safe Fixes
Trouble sleeping is common in pregnancy, and many of its causes can be eased with everyday changes rather than sleep medicine. This guide sorts the usual causes by trimester, gives one practical fix for each, and lists the signs that need a call to your maternity unit the same day.
At a glance
- Usual causes: early tiredness from hormones, a bigger bump, night-time toilet trips, and worry about the birth.
- First steps: an earlier fluid cut-off, a fixed wind-down, and lying on your side with pillows for support.
- Sleep pills and herbal sleep aids: check with your midwife, GP or pharmacist before you take any of them.
- Call the same day: a severe headache, blurred vision, sudden swelling, or a change in your baby’s movements.

Why does pregnancy make sleep so hard?
Pregnancy tiredness rarely has one cause. Usually it is several small things at once, and each one costs a little sleep. The NHS says tiredness is common, especially in the first 12 weeks, when hormonal changes can make you feel tired, nauseous and emotional. Later on, the extra weight you carry and a growing bump can make lying down uncomfortable. The need to use the toilet often can break up your night too.
Worry is the other big piece. It tends to arrive at the hour when the house is quiet, the phone screen is bright, and the mind has nothing else to do, which is why a calm wind-down matters as much as the cause itself. Dreams or nightmares about the baby, labour or birth are normal, and the NHS suggests talking about them with a partner or midwife. Relaxation and breathing techniques may help ease the anxiety that sits behind them. Simple, but not always easy.
Which causes show up in each trimester?
| Stage | Usual causes | Practical fix |
|---|---|---|
| First 12 weeks | Hormone tiredness, nausea, waking to pee | Rest in the day, drink most fluids earlier, keep the room cool |
| Middle months | Strange dreams or nightmares, worry, a growing bump | Pillows for support, a calm wind-down, talk dreams through |
| Final months | Bump size, lying down, night toilet trips, worry about labour | Side-lying with pillows, a fixed bedtime, talk worries through |
Position matters more in the later months. Lie on your side, and let pillows do the work. The NHS advises against falling asleep on your back after 28 weeks. If you wake up on your back, you can simply turn onto your side and settle again. For pillow set-ups by trimester, see our sleeping position guide.
What habits help, step by step?
- Make your last big drink about two hours before bed, and sip rather than gulp.
- Keep tea, coffee and cola out of the evening. The NHS says caffeine can make it harder to fall asleep.
- Put your rest earlier in the day. Feet up is fine, but the NHS advises avoiding afternoon or evening naps so you are tired at bedtime.
- Add gentle movement such as a lunchtime walk, swimming, or an antenatal yoga or pilates class.
- Build a 10-minute wind-down before the lights go out: dim lamps, a warm wash, and the breathing or relaxation method your antenatal class teaches.
- Keep a two-line night log for seven nights, then take it to your next antenatal visit.
If the steps above do not shift things after a couple of weeks, bring the night log to your midwife, because a clear record lets them decide what, if anything, is worth checking next, and it saves you retelling the same story at every appointment.
Insider tip: the two-line night log
Each night, write the time you woke and the reason you think woke you, such as the bump, the toilet, heartburn or worry. After a week, the pattern is easier to see than any guess, and your midwife has something concrete to work with.
Are sleep pills or herbal sleep aids safe in pregnancy?
Do not start a sleeping tablet, an over-the-counter sleep aid or a herbal sleep product without checking first. The NHS says to check with a pharmacist, midwife or GP before taking any medicine in pregnancy, including ones you buy from a shop, and it warns that not all natural remedies are safe in pregnancy.
Do not stop a prescribed medicine on your own either, because the NHS says stopping can be harmful to you and your baby, and if you are unsure whether a product counts as a medicine, ask the pharmacist before you buy it. Ask first. Every time. Sleep medicines are a clinical decision that depends on how far along you are, your health history and everything else you take, and only the people who know all of that can weigh the benefit against the risk for you. If lack of sleep is bothering you, talk to your partner, a friend, your doctor or your midwife, and ask what options suit your pregnancy.
Feeling tired will not harm you or your baby, but warning signs never wait for a better night.
When should you call your midwife or doctor?
Get urgent medical help if you are pregnant and have symptoms of pre-eclampsia. These include a severe headache that does not ease with simple painkillers, blurred vision or flashing lights, pain below the ribs, sudden swelling of the face, hands or feet, feeling very unwell, or heartburn that does not go away with heartburn medicines. If you have your maternity unit’s number, call it now.
Call the unit at once if your baby’s movements change from their usual pattern, even in the middle of the night, and do not wait for your next appointment. Call 999 in an emergency. Low mood alongside sleeplessness, such as hopelessness or losing interest in things you enjoy, also needs a talk with your doctor or midwife.
Knowing your own cause makes the next step clearer. For more calm-down routines and sleep guides, visit the Sleep & Relaxation hub, and keep any decision about sleep medicine with the people who know your pregnancy.
