Relvay makes a pregnancy pillow. We also tell you below when you should not buy one.
The short answer
Feeling much sleepier than usual is common in pregnancy, especially in the early weeks. It is worth raising with your midwife or doctor when it is new, getting worse, or getting in the way of daily life.
- Track one week: night sleep, naps, and when sleepiness hits.
- Mention it if you nod off without meaning to.
- Call sooner with dizziness, breathlessness or a racing heart.
Is it normal to sleep so much when you're pregnant?
Often, yes. The NHS says hormonal changes can make you feel tired in the first 12 weeks, and later on the extra weight you carry can do the same. It also says tiredness will not harm you or your baby, even though it makes daily life harder.
So the question is rarely "is sleepiness allowed?" It is "is my sleepiness the ordinary kind, or the kind my care team would want to hear about?" You cannot answer that from one bad afternoon. You can from a week of notes.
7:40 p.m.
I was 14 weeks and I fell asleep on the sofa before the dishes were done. Again. I had slept almost ten hours the night before. At lunch I had sat in my car in the parking lot with the seat tipped back, because I could not keep my eyes open at my desk.
Everyone said, oh, first trimester, that is normal. Maybe. But I did not know what normal was supposed to feel like, and I felt silly calling my midwife to say "I am tired". So I said nothing for three weeks.
"I am tired" is hard to bring up. "I slept ten hours and still dozed off at my desk twice this week" is easy.
How do you tell needing more rest from sleepiness worth mentioning?
Needing more rest usually means you choose when to rest and feel better afterwards. Sleepiness worth mentioning is when you fall asleep without choosing to, rest does not help, or it is new or getting worse.
| Usually ordinary tiredness | Worth mentioning to your care team | |
|---|---|---|
| When you sleep | You plan the nap or early night | You doze off in meetings, mid-conversation or as a passenger without meaning to |
| After rest | You feel better for a while | Long sleep and naps do not seem to help |
| Over the weeks | Steady, or easing | New, or clearly getting worse |
| Daily life | Harder, but you manage | Missing work, unsafe to drive, cannot look after yourself |
| Other signs | None | Dizziness, breathlessness, a racing heart, or a low mood that will not lift |
Only your care team can say what is causing it. Tiredness has many possible reasons in pregnancy, and some of them, such as low iron, are things a midwife can check for with a simple test. That is their call, not something to guess from a table.
What should go in a daytime sleepiness diary?
Five columns: last night's sleep, naps, the moments sleepiness hit, what you were doing and eating, and how you felt overall. Fill it in once in the evening, in two minutes.
| Day | Last night | Naps | Sleepiness hit | Activity and meals | Overall |
|---|---|---|---|---|---|
| Mon | 10:30 to 7, woke twice | None | 11 a.m. at desk, eyes closing | Sat most of the day, big lunch | Foggy |
| Tue | 10 to 7:30 | 20 min in car at lunch | 3 p.m., dozed in meeting | Short walk | Very tired |
| Wed | 11 to 6:30, woke three times | Sofa, 7:40 to 9 p.m. | Most of the afternoon | Skipped lunch | Wiped out |
- Write "dozed off" separately from "felt sleepy". Nodding off without choosing to is the detail your midwife will care about most.
- Note night wakings, even roughly. Broken nights can drive daytime sleepiness. If they are the bigger story, our guide to tracking why you wake at night goes deeper.
- Keep the overall column in your own words. Foggy, fine, wiped out. No score needed.
- Do not change everything while you track. One honest week beats a week of trying to look rested.
What should you ask your midwife or doctor?
Bring the diary and ask whether this level of sleepiness is expected for you at this stage, and whether any checks make sense. Let them decide what to test. Your job is to describe it clearly.
- Is this amount of sleepiness expected for me at this point in pregnancy?
- Are there any checks you would suggest, such as a blood test?
- I dozed off without meaning to on these days. Is that something to watch?
- Is it okay for me to drive when I feel like this?
- Could my night sleep be part of the problem?
- Is there anything about my work hours I should ask to change?
If you work long or irregular hours, our shift work planning checklist helps you bring a clear picture of your week.
Riley finally took three weeks of notes to her 16-week appointment. Having it on paper changed the conversation. Instead of "I am just really tired", she could point to the days she dozed off at work and the sofa naps that left her wide awake at 2 a.m. The appointment had a starting point, and they agreed to look at it again in a few weeks.
Nothing dramatic. But Riley stopped feeling silly for asking.
When should sleepiness go to someone today?
Call your midwife, doctor or maternity unit the same day if sleepiness comes with feeling faint or dizzy, getting breathless, a racing or uneven heartbeat, or you feel extremely unwell. Get urgent help for chest pain, fainting or breathlessness at rest.
- You feel extremely tired or unwell, and it is getting worse.
- Dizziness or feeling faint.
- Getting out of breath easily, or a racing heart.
- You fell asleep, or nearly did, while driving. Stop driving until you have spoken to someone.
- You feel hopeless or have lost interest in things you used to enjoy.
This diary helps you describe your sleepiness. It cannot tell you what is behind it. Only your midwife or doctor can do that.
Does sleeping more in the day make nights worse?
Sometimes. The NHS suggests avoiding afternoon or evening naps if they leave you not tired at bedtime. Your diary will show whether late naps line up with wide-awake nights for you.
If they do, the answer is usually to move rest earlier, not to push through on no rest at all. Our guide to planning naps around your real day walks through how to test that.
Frequently asked questions
Is it normal to sleep a lot in early pregnancy?
Yes, feeling very tired in the first 12 weeks is common, and the NHS links it to hormonal changes. Mention it if it is getting worse, comes with other symptoms, or you fall asleep without meaning to.
How many hours of sleep is too much when pregnant?
There is no single number that fits everyone. What matters more is whether rest helps, whether you doze off without choosing to, and whether it is new or getting worse. Bring a week of notes to your midwife.
Can sleepiness in pregnancy be a sign of low iron?
Tiredness has many possible causes in pregnancy, and low iron is one that your midwife can check for. Do not try to work it out yourself. Ask whether a test makes sense for you.
Is it safe to drive when I feel very sleepy?
If you have dozed off or nearly dozed off while driving, stop driving and speak to your midwife or doctor before you get behind the wheel again.
Should I nap if I am sleepy all day?
Rest helps many people. If late naps leave you wide awake at bedtime, try resting earlier in the day and note the effect in your diary.
If your diary shows broken nights from discomfort, our pregnancy pillow buying checklist helps you decide whether better support is worth trying.
