# Day 27: All, some, or none > Symptoms differ from person to person: every one, a few, or none. Today's scorecard tells you less than you'd think, and that's the point. - Series: Your first month of pregnancy, day by day (https://chorevia.com/learn/pregnancy-month-1), day 27 of 280, 3 weeks + 6 days - Your baby this week: a single cell, then a ball of cells - Canonical URL: https://chorevia.com/learn/pregnancy-month-1/day-27 - Last reviewed: 2026-10-22 - Publisher: Chorevia (https://chorevia.com) - Cite as: Chorevia. "Day 27: All, some, or none." Last reviewed October 22, 2026. https://chorevia.com/learn/pregnancy-month-1/day-27 This guide is general education that summarizes published research and guidance from groups like the American Academy of Pediatrics, the CDC, and the WHO. It isn’t medical advice, and every child develops on their own timeline. Your pediatrician knows your child; if something feels wrong, call them. In an emergency, call 911. The last day of week 3. Today is a quiz you can't fail: a scorecard of early symptoms, and the honest news that the score tells you very little. ## Your baby A ball of cells, implanted in the wall of your uterus, with the cluster that will form the placenta supplying nutrients and oxygen ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo)). Pregnancy usually lasts about 40 weeks, just over 9 months, counted from the last menstrual period, and this is week 3 of the first trimester, weeks 1 to 12 ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo)). No source gives a length this week; the measuring starts next week. ## Your body Symptoms differ from person to person: some people get every common symptom, some a few, some none ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo/signs)). A missed period is the main sign, though many notice other symptoms first ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo/signs)). And the timing is loose: fatigue can appear as early as 1 week after conception, breast tenderness, swelling, or tingling as early as 1 to 2 weeks, nausea anywhere from 2 to 8 weeks after conception and at any time of day, and mood swings a few weeks after ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo/signs)). Frequent urination is on the list because hCG, produced in the first few weeks, increases blood flow to the pelvic region ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo/signs)). So whatever you feel this evening, or don't, is inside the normal range. Which is why today's exercise is deliberately a little pointless. ## Try today ### The symptom scorecard - **Time:** 3 minutes, pen and paper 1. Draw five boxes and label them: fatigue, sore breasts, nausea, mood swings, peeing more ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo/signs)). 2. Tick the ones you have today. Leave the rest empty; don't go looking. 3. Add a sixth box for the main sign, a missed period, and tick it only if yours is actually late ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo/signs)). 4. Count the ticks, then read this line again: every common symptom, a few, or none are all normal ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo/signs)). **Make it work:** Keep the card. Next week's may look different, and the first visit is easier with dates written down. ## Watch for - **Normal:** a period that's late and a test that isn't positive yet; most home tests don't give accurate results one day after a missed period ([OWH](https://womenshealth.gov/pregnancy/you-get-pregnant/knowing-if-you-are-pregnant)). **Call your provider** if you miss a period, whatever the test says; a missed period doesn't always mean pregnancy, and NICHD says women who miss one should see their provider ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo/signs)). - **Normal:** sore, swollen, or tingly breasts ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo/signs)). **Call 911** for chest pain or a fast-beating heart, or trouble breathing ([CDC](https://www.cdc.gov/hearher/maternal-warning-signs/index.html)). - **Normal:** mood swings from hormonal changes, which can begin a few weeks after conception ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo/signs)). **Call your provider** as soon as possible if you think you have depression; in a crisis, call or text 988 ([CDC](https://www.cdc.gov/reproductive-health/depression/index.html)). ## For you Headache, fatigue, and breast tenderness can all appear before a missed period ([OWH](https://womenshealth.gov/pregnancy/you-get-pregnant/knowing-if-you-are-pregnant)). So can nothing. If your scorecard is empty, you are not behind, and you are not less pregnant than the friend who was sick from day one; "none" sits on NICHD's list right beside "every common symptom" ([NICHD](https://www.nichd.nih.gov/health/topics/pregnancy/conditioninfo/signs)). If you're the partner: she may feel nothing and still be sure, or feel everything and still doubt it. Believe whichever she reports, and don't audit the card. ## Sources - National Institute of Child Health and Human Development. "About Pregnancy."
