You were probably hoping it would have eased off by now.
Seven weeks in, and instead of things settling, the nausea has often gotten worse, not better. The exhaustion that hit at five and six weeks has not lifted — if anything, it has deepened. Foods you loved a month ago have become genuinely repulsive to you, sometimes to the point where you cannot stay in the same room as them. And somewhere underneath all of that, you are trying to hold onto the fact that this is good news. That every wave of nausea is, in its own unpleasant way, evidence that your hormones are doing exactly what they are supposed to be doing.
I am not going to pretend that reframe makes the actual experience of week seven easier in the moment. But I do want you to know what is happening, both in your body and in your baby’s, because seven weeks is doing an extraordinary amount of work despite how miserable it can feel from the inside.
Your baby at 7 weeks — the brain working faster than it ever will again
Your baby is now approximately 9.5-12mm long, roughly the size of a blueberry, and has nearly doubled in length in just one week. Baby is still curled into the characteristic C-shape of an early embryo, but is becoming recognisably more complex with each passing day.
Baby’s brain is growing at a pace that will genuinely never be matched again at any later point in their life with thousands of new brain cells being produced every single minute. It is difficult to overstate how extraordinary this is. The organ that will eventually let them recognise your face, learn language, fall in love, and build an entire interior world is, this week, constructing itself at a speed that defies easy comprehension.
Baby’s facial features are becoming more distinct. The earliest versions of their eyes, nostrils, ears, and mouth are forming, not yet anything you would recognise as a face, but the structures from which that face will eventually emerge. The limb buds that appeared as small protrusions last week are lengthening now, with tiny paddle-like structures beginning to form at their ends, the earliest versions of what will become their hands and feet.
Baby’s heart, which began beating last week, continues working and becoming gradually more efficient at circulating blood through their rapidly developing body. Baby’s liver, kidneys, lungs, and digestive system continue forming, and the umbilical cord (their literal lifeline for the next eight months) is now functioning, carrying oxygen and nutrients from your body to theirs and removing waste in the other direction.
Why this is often the hardest week so far
If your symptoms have intensified rather than settled, you are not imagining it and you have not done anything wrong. Pregnancy hormones — particularly hCG and progesterone — continue rising sharply through these weeks, typically peaking somewhere between weeks nine and eleven. Week 7 often sits right in the middle of that climb, which is precisely why so many women report this as one of the most physically difficult stretches of the entire first trimester.
Morning sickness frequently peaks around now. Nausea that may have been mild or intermittent in previous weeks can become near-constant. Vomiting may begin or worsen if it had already started. Food aversions can become more specific and more intense, not just a general loss of appetite, but a visceral, immediate rejection of particular smells, textures, or foods that were entirely unremarkable to you a few weeks ago. None of this reflects how the rest of your pregnancy will go. It reflects where your hormone levels currently sit, and they will not stay this high forever.
Fatigue at seven weeks can feel genuinely disabling. Not tired in the way a busy week makes you tired, but a depth of exhaustion that no amount of sleep seems to resolve. This is your body simultaneously building a placenta, supporting extraordinarily fast fetal brain development, and managing hormone production at levels it has never previously needed to sustain. The tiredness is the visible cost of work that is, right now, entirely invisible.
Breast changes often continue intensifying: tenderness, fullness, heaviness, and for many women, noticeably darker areolas and more visible veins across the chest as blood flow increases.
Increased saliva is a strange but genuinely common symptom some women notice around this stage — an excess that can feel bizarre and is sometimes linked to nausea, occasionally even preceding it as a kind of early warning sign. It is harmless, if uncomfortable, and tends to ease as the first trimester progresses.
Bloating, constipation, and general digestive sluggishness are common as progesterone continues slowing the digestive process. This combination, nauseous, bloated, and exhausted simultaneously, is one of the more thoroughly unpleasant aspects of early pregnancy, and it is entirely normal even though nobody warns you quite how unglamorous these weeks can be.
Emotional fluctuation: excitement, anxiety, tearfulness, and occasional flashes of something close to grief for the version of your life before this, all cycling through within a single day, is extremely common given both the hormonal intensity of this stage and the genuine weight of what is changing in your life.

If your symptoms suddenly seem to lessen
This is a worry that comes up often around this stage, and it is worth addressing directly: symptoms can fluctuate day to day, and a temporarily quieter day does not automatically indicate a problem. Some days within the first trimester genuinely do feel easier than others, for reasons that are not always clear. If a reduction in symptoms is sudden, dramatic, and sustained over several days — particularly if accompanied by bleeding or pain — contact your gynaecologist to discuss it. But the occasional good day in the middle of an otherwise difficult stretch is common and is not, on its own, cause for alarm.
What a 7-week ultrasound often shows
By seven weeks, an ultrasound frequently shows the gestational sac, the yolk sac, a clearly visible embryo, and detectable cardiac activity — often more clearly than at six weeks, since the embryo and heart have both grown and matured in the intervening days. For many parents, this is the appointment where pregnancy properly sinks in. Seeing a small, rapidly flickering heartbeat on the screen, even when everything else about the image is too small to interpret, is for many women and their partners one of the most emotional moments of the entire pregnancy so far.
Eating when nothing sounds appealing
If food aversions have become severe by week seven, the most useful mindset shift is to stop aiming for balanced nutrition in the conventional sense and focus instead on simply getting enough in, in whatever form is currently tolerable.
Small, frequent meals remain more manageable than larger ones for most women at this stage. If protein is tolerable, prioritise it where you can — eggs, yoghurt, nuts, whatever specific protein source has not yet become an aversion for you, since these tend to be more satisfying and sustaining than carbohydrate-only snacking. If almost everything feels difficult, bland starches — crackers, plain toast, rice — are a reasonable foundation to rely on for a stretch, and there is no need to feel guilty about a diet that looks nothing like the balanced plate you imagined eating during pregnancy. This phase does not last the whole nine months. Hydration matters more than variety right now — small, frequent sips rather than large glasses, particularly if nausea makes drinking difficult.
If vomiting has become frequent enough that you cannot reliably keep fluids down, or if you are losing weight rather than simply struggling with appetite, contact your gynaecologist. This may be hyperemesis gravidarum, which is more than ordinary morning sickness and benefits from medical management rather than simply being endured.
What to do this week
If you have not yet had your first antenatal appointment, this is often the week it happens — many Mauritius gynaecologists schedule the first visit around six to eight weeks, sometimes with an early scan included.
Continue folic acid and your prenatal vitamins daily, even on days when keeping anything down feels like an achievement.
Protect your rest aggressively. This is not a week for pushing through tiredness to prove anything. If you need an early night, or a nap, or to decline plans, that is the right call.
Lower your expectations of yourself around food for now. Bland, repetitive, imperfect eating is acceptable during a week like this one. It will not last.
Stay as hydrated as you can manage, particularly given the Mauritius heat compounding the effects of nausea and fatigue.
Next week brings another significant milestone — fingers and toes beginning to form, facial features becoming more defined, and your baby starting to look, for the first time, recognisably like a very small human rather than the curled embryonic shape of these earliest weeks.
