14 weeks pregnant: what is happening this week

Fourteen weeks — welcome to the second trimester.^[1] Your baby is around 8.5 cm from head to bottom now, about the size of a kiwi fruit.^[1] You may be starting to feel less tired and less sick, though every pregnancy makes its own schedule.^[1] This is a good week for practical footing: check your dates, keep antenatal care moving, and know which symptoms belong with a healthcare professional rather than a guess. Here is week 14, for both of you.

Watch: your baby at week 14

A calm, 30-second recap of week 14, from our channel @duedatelab.

What is happening at 14 weeks pregnant

The count still runs from the first day of your last period — which can make the number feel ahead of time since conception, and which remains exactly the count your due date, appointments, and scan windows are built on. The practical question at this stage is rarely whether the label is exact to the day. It is whether your dates, appointments, and anything you are tracking line up well enough for the next step.

The trimester turn comes with a carefully hedged promise: you may be starting to feel less tired and sick — may.^[1] Some people get the lift right on cue. Others carry nausea, tiredness, headaches, bloating, sore breasts, or dizziness a while longer.^[1] A new trimester label does not switch symptoms off, and it does not make a concern less worth raising.

Pregnancy may also be getting more practical this week — more visible, more planned. Work, appointments, scan timing, how and when to tell people. Keep the planning separate from symptom-reading: the calendar decisions are yours to make on your own schedule, and the symptom questions belong with your care route.

If you keep one habit from the first trimester, keep the note-taking: dates, questions, anything that changed. The second trimester tends to fill up with appointments, and arriving with your own record makes each one quicker and calmer.

Your baby's development this week

About 8.5 cm now, kiwi-sized.^[1] Approximate, as always — scan method, timing, and dating all move individual measurements, and yours are read by your care team. What the number tells you is scale: growth is brisk, and nearly all of it is still beyond feeling.

The quiet hero of week 14 is the placenta. It is full of blood, pumping nutrients, oxygen, and hormones in and carrying waste products such as carbon dioxide out.^[1] It is the whole support system between your body and your baby, working through the umbilical cord — nothing you monitor from home, but the reason blood-pressure checks, urine checks, and scan timing keep mattering as pregnancy continues.

Your baby is kicking around in there, and you probably cannot feel it yet.^[1] Both halves of that sentence are true, and the gap between them is normal: people usually start feeling movement between 16 and 24 weeks, and with a first baby often not until after 20 weeks.^[4] At 14 weeks, silence from the inside is not a warning sign of anything.

And one detail worth knowing just because it is wonderful: your baby swallows small amounts of amniotic fluid, which passes into the stomach, and the kidneys pass the fluid back out as urine.^[1] The whole loop is already running. File it under “what is happening”, not “what should I check”.

What may be happening to you

You may be starting to feel less tired and sick, with your appetite returning as your energy levels come back.^[1] If the early weeks were rough, that is a genuinely good sentence to read — just keep it as a possibility rather than a promise. Feeling better is the stage for some people; still feeling rough is the stage for others.

The week-14 maybe-list: headaches, nosebleeds, constipation, indigestion and heartburn, sore breasts, leg cramps, dizziness, urine infections, vaginal infections, and light spotting — with any bleeding checked by a healthcare professional.^[1] The list is broad because symptoms do not follow a clean weekly schedule; the routing rule underneath it never changes.

On food: your baby does not need any extra calories at this point.^[1] Which is not an instruction to ignore hunger — healthy snacks between meals are perfectly reasonable — just the reason “eating for two” does not match the guidance at this stage. Personal nutrition questions sit best with your midwife, GP, or local antenatal team.

And the telling-people question, since it often lands this week: many women tell their employer after the first pregnancy scan at around 12 weeks, and work rights and risk assessment are worth thinking about around now.^[1] Practical prompts, not a public timeline you owe anyone. Announce on your own schedule.

And if you are still waiting to feel better: fourteen weeks of feeling rough is genuinely tiring. Be as patient with yourself as you would be with a friend in the same week — the stage passes at its own pace, not the calendar’s.

Safety: when to get help in mid pregnancy

Bleeding in pregnancy can sometimes need urgent assessment, so the route is to get advice rather than interpret the colour, amount, or timing on your own.^[2] Symptoms such as severe headache, vision problems, pain below the ribs, sudden swelling, vomiting, and feeling very unwell can be serious and need checking immediately.^[3]

Movement needs the same caution. Movement is usually felt between 16 and 24 weeks, and first pregnancies may notice it later than repeat pregnancies.^[4] At 14 weeks, you should not expect to feel movement yet. Once movements have started, a reduced, stopped, or changed usual pattern should be handled through a midwife or maternity unit immediately.^[4]

Booking your antenatal care

By 14 weeks, many readers will already have started antenatal care, but paths vary. The practical step is to start antenatal care as soon as possible after finding out you are pregnant, with the first midwife appointment before 10 weeks where possible.^[5] If that has not happened, the useful next step is to use your local pregnancy-care route rather than assuming the timing has failed. If you are more than 10 weeks pregnant, you should still self-refer to start care as soon as possible.^[5]

The appointment schedule starts to shift after the early booking and dating-scan period. An ultrasound scan is offered at 11 to 14 weeks to estimate when the baby is due, and another ultrasound scan is offered at 18 to 21 weeks to check physical development.^[5] That makes week 14 a useful moment to confirm what has already been booked and what is coming next.

Routine antenatal care includes checks such as measuring blood pressure and testing urine for protein.^[5] Those checks matter because some issues are picked up through appointments rather than symptoms you can reliably interpret at home. If you are unsure whether you have the right appointment, scan, or local booking pathway, use the contact details from your maternity notes, local NHS trust, GP, or midwife route.

Use our Due Date Calculator

Use the Due Date Calculator if you want to check how your week count lines up with an estimated due date. The calculator uses the first day of your last period as the starting point, which is the same convention used across these week-by-week pages. It can help you compare your own dates with appointment windows, but it does not interpret symptoms or scan findings.

If someone is asking how far along you are in months, the 14 weeks pregnant in months page gives the conversion separately. That can be useful for family conversations, but clinicians usually use weeks because weeks are more precise for pregnancy dating, appointments, and scans.
