Mood swings are expected this week. Today is about telling an ordinary low day from something that needs help, and where to turn.
- Size this week

- around 10 mm from head to bottom

Seven weeks and five days. Today is about naming how you feel, on paper if not out loud, and knowing where the line is between an ordinary low day and the kind that needs a call.
Your baby

Around 10mm from head to bottom, about the size of a grape (NHS). The brain, face and eyelids are developing this week (NHS). Those eyelids have a long job ahead: they close during weeks 11 to 14 and don't reopen until about week 28 (MedlinePlus).
Your body
Mood changes are on the NHS's list for this week, alongside tiredness, nausea, sore breasts, headaches and cramping (NHS). Mood swings from hormonal changes can begin a few weeks after conception (NICHD). A swing, though, is not the same as a mood that stays low most days.
The CDC's numbers are plain: about 1 in 10 women of reproductive age in the US reported symptoms suggesting a recent major depressive episode, and depression is common and can be treated; most people, even with severe depression, improve with treatment (CDC). Anxiety during and after pregnancy is as common as depression (AAP). Looking after your mental wellbeing is on the NHS's to-do list for the week, next to the folic acid (NHS).
Try today
The feelings thermometer
Time: 1 minute a night, for a week
Tonight, give the day a number from 1 to 10, where 10 is the best you feel. Write it with the date.
Add three words about why: tired, nauseous, a good call with a friend.
Do the same every night for a week. Don't average the numbers and don't argue with them.
If the numbers stay low for two weeks, take the page to your provider. The CDC's advice is to seek treatment as soon as possible if you think you have depression (CDC).
Make it work:The scale is ours, not a medical test. It catches a pattern before you'd have to remember one.
Watch for
Normal
a mood that lifts and drops in the same afternoon; mood changes are on the NHS's list this week (NHS).
Call your provider
as soon as possible if you think you have depression; it can be treated (CDC).
Normal
wanting a nap by mid-afternoon; tiredness is on the same list (NHS).
Call your provider
for overwhelming tiredness, which is on the CDC's list of urgent maternal warning signs (CDC).
Normal
a worry that comes and passes.
Call your provider
for scary, upsetting thoughts that don't go away, extreme sadness or anger, or losing interest in things you used to enjoy (AAP).
Normal
reading this bullet and finding none of it applies.
For you
If the number tonight is low, you did not cause it. The AAP's words: "These feelings are not something you caused by doing or not doing something." They can be treated if you seek help, they won't go away on their own, and several medications that treat depression and anxiety are safe for pregnant women, with counseling as another option (AAP). A previous or family history of depression, and little or no social support, may raise the risk (CDC), which is a reason to tell your provider your history, not a verdict.
If you're the partner: ask for the number, not a summary. And the CDC's line is for you: don't leave another person alone if she or he is in crisis (CDC).
