Why do I feel so anxious in the second trimester?

It's not only your hormones

Hormone levels keep shifting through pregnancy, and cortisol (the body's main stress hormone) tends to rise as the pregnancy goes on, so your system is carrying a real physical load. That backdrop can leave you more sensitive than usual.

But your hormones are rarely the whole story. The second trimester is, if anything, hormonally steadier than the first, once the early surge of pregnancy hormones settles. For most people, the reason for feeling anxious has more to do with what’s happening around them.

The second trimester is also when pregnancy often starts to feel more real. Appointments are usually still few and far between, which in itself can be cause for worries, and they’re also becoming more focused on the baby's development. You may have started to tell more people, and others might now notice that you’re pregnant. Many expecting parents experience more urgency to come up with plans around childcare, finances, parental leave or what life will actually look like after birth. That can bring a growing sense of excitement as well as new layers of responsibility and worry.

When the fear of loss doesn't switch off

The chance of miscarriage drops significantly after the first trimester, which to some people, specifically those around you, sounds like permission to relax. For many, that fear transforms rather than switching off. Now that you've made it this far, the stakes can feel higher.

Relief at clearing the first trimester and a quieter, steadier dread can absolutely sit side by side. For example, the 20-week anatomy scan is often a major event for many expecting parents. It’s something many parents look forward to with both worry and anticipation, as this is a major pregnancy milestone. During this scan, the development of body parts and organs is checked, and the scan can also detect certain congenital conditions.

At this point in the pregnancy, an ultrasound technician can also check for the sex of the baby. While they aren’t always able to disclose this at the time of appointment, your pregnancy care provider will often be able to share that information with you. For many parents, it’s also around this time that you’re shifting from your regular healthcare provider (e.g., family doctor, nurse practitioner) to another care provider who will follow you through pregnancy, birth and postpartum (e.g., Family-Centred Maternity Care doctor, midwife, OB).

New information being revealed on the scan and the transition to a new care provider can bring a lot of worry and concern. Anxiety tends to ask for certainty, and pregnancy is one of those experiences where complete certainty simply isn't available.

If you're the non-birthing parent or support person: You may be watching someone brace for bad news at what's meant to be a happy milestone, unsure whether to reassure or just sit with them. You might have your own feelings to work through as well. You don't have to fix the worry in your loved one. Pick one concrete thing: come to the next scan, or take a recurring task off their plate without being asked. And keep an eye on your own stress levels, as this stretch can ask a lot of you too.

Anxiety rarely has a single cause

Anxiety usually grows out of several overlapping pressures.

A prior history of anxiety or depression is one of the strongest predictors, and it sits alongside things like recent stressful events, relationship strain, a small support network, financial pressure and high expectations of what pregnancy is "supposed" to feel like.

The modern pressure to do everything perfectly, and be fully prepared, adds another layer. Fed by carefully curated images of other people's pregnancies and marketing strategies, the practical to-do list can turn into a source of dread, where falling "behind" starts to feel like failing. None of this means you're doing it wrong. For some people, the second trimester is also an opportunity to slow down and notice how they're feeling. The intensity of the first trimester can be all about getting through the day. Once the nausea eases and energy returns, there might now be more mental space, and sometimes anxiety rushes in to fill it.

When the worry locks onto the baby

For many expecting parents, pregnancy anxiety often takes on a specific shape: it tends to zero in on the baby's health and your ability to be a good parent. The second trimester is often when pregnancy becomes tangible in a new way, and more visible for people around you as well. You may see more of the baby on ultrasound, learn more about their development or start feeling movement. The attachment grows and so can the instinct to protect. This is often when you first feel movement, which can flip between deeply reassuring and mildly alarming. "Is the baby moving enough?" becomes a constant question.

A sharpened protective instinct is part of becoming a parent. It tips into a problem when the checking takes over. For example:

• Asking for reassurance, getting it and needing it again soon after — this could look like checking the baby’s heartbeat with a doppler machine multiple times a day, without any medical indication to do so
• Counting and documenting movements or searching symptoms online to the point where it takes up a large part of your day
• Replaying worst-case scenarios in your head that you can't switch off, even when you want to focus or sleep

The relief these actions bring is real but brief, and the habit tends to feed the worry rather than settle it.

Practical ways to work with the worry

A couple of small, repeatable tools are often more useful than a vague instruction to calm down:

• Slow your breathing when it spikes. Breathe in through your nose for a count of five, let it reach your belly, then breathe out through your mouth for another count of five. Focusing and elongating your breath out can be specifically helpful. Practise it when you're calm, so it's there when you're not.
• Question the worst-case thought. When your mind jumps to catastrophe, ask how likely it really is, and what you'd say to a friend thinking the same thing.
• Monitor without spiralling. If you're tracking movement, do it in the calm, regular way when and how your care provider suggests, rather than on a loop or by creating your own system.
• Protect the basics. Prioritize sleep and rest, do gentle movement (approved by your healthcare provider) and tell one trusted person what's going on — this can take the edge off, and remind you that you don’t have to carry this alone.

When anxiety is worth acting on, and how to start

Most pregnancy worries come and go. It's worth closer attention when worry settles in and stays. Signs that you might want to bring this up with your care provider include:

• Anxiety most days for two weeks or more
• Trouble sleeping even when you're exhausted and there’s no physical reason to stop you from sleeping (like having to pee constantly or not being comfortable)
• Frequent racing or intrusive thoughts you can't stop
• Physical symptoms like a tight chest or pounding heart
• Worry that's getting between you and eating, functioning or the people around you

Anxiety during pregnancy is no indication of what kind of parent you are right now, nor does it predict how you will parent once the baby is here. Many people who spend months worrying about whether they are coping "correctly" go on to navigate parenthood thoughtfully and well.

Perinatal anxiety can be tricky to recognize, as some form of worry is expected, and it can be hard to track when anxiety moves beyond typical into the territory of perinatal anxiety, but it’s usually temporary and very treatable. Most parents with perinatal anxiety have seen huge improvements with counselling, talk therapy, learning practical skills and increased support throughout the perinatal period. Anxiety can be easier to shift the earlier you catch it. The hardest step is usually the first sentence. You don't need the perfect words. Something like, "I've been feeling anxious most days for a couple of weeks and I wanted to mention it," can be enough to open the door.

If you ever have thoughts of harming yourself or someone else, that needs same-day support. In Canada, call or text 9-8-8 any time, or call 9-1-1 in an emergency. Reaching out is the right step, not an overreaction.

If anxiety has been with you most days for the last two weeks, that's worth bringing up at your next appointment, or making a specific appointment for, if you don’t have an appointment coming up soon. Our [Services Finder] can also help you find someone who specializes in perinatal anxiety. You don't need to know exactly what's wrong to use it.
