The NHS puts two escalation levels above the routine advice.

Contact a GP immediately if you, or a friend or relative who is pregnant, starts hearing or seeing things that are not real (hallucinations), or develops strong beliefs not shared by others (delusions). If you cannot contact a GP, call 111 or find your nearest A&E.

Call 999 if you think there is a danger that you might harm yourself or others, or you are worried that someone else might harm themselves or others.

The HSE puts emotional distress and mental health crisis on the same immediate-contact list as bleeding, severe headache and a change in your baby's movements. That placement is deliberate.

What antenatal depression is

The NHS names it and normalises it in one line: "You can get depression when you're pregnant. It's called antenatal depression. With help and support most people with antenatal depression are able to manage the condition."

It then draws the line between ordinary pregnancy mood and something more: "Some mood changes are normal in pregnancy, like feeling tired or irritable. But if you often feel low and hopeless and no longer enjoy the things you used to, talk to a midwife or GP."

The signs it lists are:

feeling sad, a low mood, or tearful a lot of the time
feeling irritable, or getting angry easily
losing interest in other people and the world around you
not wanting to eat, or eating more than usual
negative thoughts, such as worrying you will not be able to look after your baby
feeling guilty, hopeless or blaming yourself for your problems
having problems concentrating or making decisions

Why it gets missed

Several of those overlap with things pregnancy does anyway. Tiredness, irritability, changes in appetite and difficulty concentrating are all on the ordinary list too. The NHS tiredness page makes a related point about sleep: "Occasionally, sleeplessness — when accompanied by other symptoms — can be a sign of depression. If you have any of the other symptoms of depression, such as feeling hopeless and losing interest in the things you used to enjoy, speak to your doctor or midwife."

The distinguishing features are duration, pervasiveness and the loss of pleasure. Being tired and snappy for a week is pregnancy. Feeling flat and hopeless most days for a fortnight, with things you used to enjoy no longer registering, is worth naming.

Why it is worth treating now rather than later

The NHS gives the reason directly: "If antenatal depression is not treated your symptoms can get worse and may continue after the baby is born (postnatal depression). So it's important to get help if you need it."

Antenatal depression is one of the strongest predictors of postnatal depression, which is exactly why NICE's guideline on antenatal and postnatal mental health (CG192) covers pregnancy and the postnatal year together rather than separately, and why questions about mood appear in antenatal appointments from booking onwards.

What treatment looks like

The NHS sets out three tiers.

Self-help. A GP or midwife may recommend talking about your feelings to a friend, family member, doctor or midwife; calming breathing exercises if you feel overwhelmed; increasing physical activity if you can, because it can improve mood and help you sleep; attending antenatal classes to meet others expecting babies at the same time; and eating a healthy diet.

Psychological therapy. A GP may recommend a self-help course or refer you for NHS talking therapies, offered face to face or online. The NHS is honest about the wait: "You may have to wait several weeks to get an appointment."

Antidepressants. These may be recommended for moderate or severe depression if you do not want psychological therapy, if therapy has not worked, or if you prefer medicine, and some people benefit from both together. The NHS says to talk to a GP about antidepressants that are safer to take during pregnancy, that "the doctor will usually offer the type with the lowest risk for you and your baby", and that they will explain the risks and benefits so you can decide together.

If you are already on medication

The NHS instruction is unambiguous: "If you are already taking any prescribed medicine when you find out you are pregnant, then you should tell your doctor or specialist as soon as possible. Do not stop taking the medicine until you have spoken to them."

Stopping antidepressants abruptly on a positive test is common and is specifically what the guidance asks you not to do. The conversation about what to change belongs with the person who prescribed it.

If you have an existing mental health condition

The NHS says you should be referred to your local perinatal mental health service if you are pregnant and have a long-term mental health condition such as bipolar disorder, schizophrenia, obsessive compulsive disorder, or an eating disorder such as anorexia. These services provide specialist support during and after pregnancy, and you should be offered regular appointments with a midwife experienced in helping people with your condition.

If that referral has not been mentioned to you, it is entirely reasonable to ask for it by name.

Partners and family

Antenatal depression is often noticed by someone else first, and that person is frequently unsure whether saying something would make it worse. It does not. The NHS directs its urgent advice at relatives as well as at the person themselves, wording it as "you, or a friend or relative who is pregnant". Encouraging someone to mention their mood at a midwife appointment, or offering to be in the room, is a reasonable and useful thing to do.

How to start the conversation

The most useful framing is the NHS's own criterion: say how it is affecting your daily life, rather than trying to justify why you feel it. "I have not enjoyed anything for three weeks", "I cry most days", "I cannot make simple decisions" are all more useful to a midwife than an attempt to explain what caused it.

You will be asked about your mood at antenatal appointments regardless. Answering honestly is not an escalation; it is what those questions are for. The NHS's parallel page on anxiety adds the reassurance worth carrying into the room: doctors and midwives are used to treating this, and you are not going to be judged.
