Mood swings in the second trimester: why, and what helps

What is driving it

Hormones: oestrogen and progesterone rise steeply and affect the same brain chemistry that mood medication targets. This is physiology rather than character.

Sleep: disturbed from the second trimester by the bladder, heartburn, restless legs and an unfamiliar sleeping position. Sleep loss alone produces most of what gets called moodiness.

Physical discomfort, body changes, and the loss of things you used to do — none of which is trivial.

And the situational load, which is heavy in Indian families: advice from everyone, decisions about work and leave, in-law dynamics, money, and the pressure to be visibly happy at all times.

What helps

Sleep first. Fix what can be fixed — earlier dinner for heartburn, a pillow between the knees, a fan, a shorter evening — because everything else improves when sleep does.

Movement: thirty minutes of walking most days measurably improves mood in pregnancy and is safe in an uncomplicated one.

Eat regularly. Long gaps produce low blood sugar, which feels exactly like irritability.

Say it out loud to someone who will not immediately reassure you. Antenatal classes, a friend who has been pregnant, or a sister are more useful than a partner who wants to fix it.

Reduce the input: mute the group chats, limit the advice-givers, and stop reading forums at 2 a.m.

And ask for practical help specifically rather than generally — 'take over the cooking on Sundays' works; 'I need support' gets agreement and no action.

For partners

Do not open with solutions. Listen, and say the thing that is actually true: this is hard, you are doing a lot, what would help right now.

Take a category of work entirely rather than helping when asked. Owning the shopping, the appointments or the cooking removes mental load, which is what exhausts.

Come to appointments. Being present at a scan or a check changes how included a partner feels and how informed you are.

And watch for the difference between mood swings and depression. Partners often notice first, and saying it gently — 'you have seemed low for weeks, shall we talk to the doctor' — is one of the more useful things a husband can do.

When to see a doctor

Antenatal depression and anxiety are common — roughly one in eight to one in ten pregnancies — and are treatable. Signs: low mood most of the day for two weeks or more, loss of interest in everything, hopelessness, guilt, panic, inability to sleep even when the baby allows it, appetite changes beyond the usual, or intrusive frightening thoughts.

Seek help urgently for any thought of harming yourself, feeling unable to go on, or an inability to function. Tele-MANAS on 14416 is free, confidential and round the clock; 112 is the emergency number.

Also tell your obstetrician if you are already on mental-health medication — it should be reviewed rather than stopped, because untreated illness carries risks of its own.

Frequently asked questions

Q: Is it normal to cry every day? — Occasional tearfulness is very common. Crying every day for weeks, with low mood and loss of interest, is worth raising with your doctor.

Q: Do mood swings affect the baby? — Ordinary emotional ups and downs do not. Severe, prolonged untreated depression or anxiety is associated with poorer outcomes, which is a reason to treat it rather than to feel guilty about it.

Q: Can I take medication for anxiety in pregnancy? — Some options are used in pregnancy under specialist advice. Never stop an existing medicine on your own, and never start one without telling the prescriber you are pregnant.

Q: My family says I should stay happy for the baby's sake. — Well-meant and unhelpful. Feelings are not chosen, and the useful response to low mood is help rather than instruction.
