Some early signs of pregnancy may show up around the time you've missed a period — or a week or two before or after.
Not every woman has early pregnancy symptoms, but many do. About half of women have symptoms like nausea, vomiting, fatigue, frequent urination, and breast tenderness and swelling by the time they're 5 weeks pregnant, 70 percent have pregnancy symptoms at 6 weeks along, and roughly 90 percent have pregnancy symptoms by the time they're 8 weeks pregnant. If you start to feel some of the early pregnancy symptoms below not all women get them and you're wondering why you haven't gotten your period, you may very well be pregnant.
If you're usually pretty regular and now have missed your period, you may decide to do a pregnancy test before you notice any other symptoms. But if you're not regular or you're not keeping track of your cycle , nausea and breast tenderness and extra trips to the bathroom may signal pregnancy before you realize you didn't get your period.
If you're newly pregnant, constipation may be the first symptom you notice. It's caused by an increase in the hormone progesterone, which relaxes smooth muscles throughout the body, including the digestive tract. This means that food passes through the intestines more slowly.
It's common to have mood swings during pregnancy, partly because of hormonal changes that affect neurotransmitters chemical messengers in the brain. Everyone responds differently to these changes. Some moms-to-be experience heightened emotions, both good and bad, while others feel more depressed or anxious. Note: If you've been feeling sad or hopeless or unable to cope with your daily responsibilities, or you're having thoughts of harming yourself, call your healthcare provider or a mental health professional right away.
Hormonal changes in early pregnancy may leave you feeling bloated, similar to the feeling some women have just before their period. That's why your clothes may feel more snug than usual at the waistline, even early on when your uterus is still quite small. Shortly after you become pregnant, hormonal changes prompt a chain of events that raise the rate of blood flow through your kidneys.
This causes your bladder to fill more quickly, so you need to pee more often. Frequent urination will continue — or intensify — as your pregnancy progresses. Your blood volume rises dramatically during pregnancy, which leads to extra fluid being processed and ending up in your bladder. The problem is compounded as your growing baby exerts more pressure on your bladder. Feeling tired all of a sudden? No, make that exhausted. No one knows for sure what causes early pregnancy fatigue, but it's possible that rapidly increasing levels of the hormone progesterone are contributing to your sleepiness.
Of course, morning sickness and having to urinate frequently during the night can add to your sluggishness, too. You should start to feel more energetic once you hit your second trimester, although fatigue usually returns late in pregnancy when you're carrying a lot more weight and some of the common discomforts of pregnancy make it more difficult to get a good night's sleep.
One common pregnancy symptom is sensitive, swollen breasts caused by rising levels of hormones. The soreness and swelling may feel like an exaggerated version of how your breasts feel before your period. Your discomfort should diminish significantly after the first trimester, as your body adjusts to the hormonal changes.
It seems counterintuitive: If you're trying to get pregnant, the last thing you want to see is any spotting or vaginal bleeding. But if you notice just light spotting around the time your period is due, it could be implantation bleeding. No one knows for sure why it happens, but it might be caused by the fertilized egg settling into the lining of your uterus. Note: About 1 in 4 women experience spotting or light bleeding during the first trimester.
It's often nothing, but sometimes it's a sign of miscarriage or ectopic pregnancy. If your bleeding is severe or accompanied by pain or lightheadedness, or if you're at all concerned, call your doctor or midwife.
For some women, morning sickness doesn't hit until about a month or two after conception, though for others it may start as early as two weeks. And not just in the morning, either: Pregnancy-related nausea with or without vomiting can be a problem morning, noon, or night.
Most pregnant women with nausea feel complete relief by the beginning of the second trimester. For most others it takes another month or so for the queasiness to ease up. A lucky few escape it altogether. If you've been charting your basal body temperature and you see that your temperature has stayed elevated for more than two weeks, you're probably pregnant. In spite of what you might read on the box, many home pregnancy tests are not sensitive enough to reliably detect pregnancy until about a week after a missed period.
So if you decide to take a test earlier than that and get a negative result, try again in a few days. Remember that a baby starts to develop before you can tell you're pregnant, so take care of your health while you're waiting to find out, and watch for more early pregnancy symptoms.
It's impossible to predict when pregnancy symptoms will start, because it's different for every person and even every pregnancy! Some women feel the first twinges of pregnancy a week or two after conceiving, while others don't feel any different for a few months. In the best study on this question to date, women who were trying to get pregnant kept daily records of their symptoms from the time they stopped using birth control until they were 8 weeks pregnant.
That's counting eight weeks from the first day of their last menstrual period. Expecting mothers frequently experience mood swings. This is primarily caused by the hormonal changes that affect the neurotransmitters of the brain. Some may experience elevated highs and lows, and others alternate between states of happiness and depression or anxiety.
Some women prefer to go directly to a counselor or mental health professional. Lower backaches are common. Food cravings or food aversions. The food expecting women crave or seek to avoid varies and is quite sporadic. These cravings or aversions can occur early in pregnancy or anytime throughout your pregnancy.
Darkening of the Areolas. Hormonal changes during early pregnancy can cause you to feel bloated, similar to how you might feel at the start of a menstrual period. Light spotting. Sometimes a small amount of light spotting is one of the first signs of pregnancy. Known as implantation bleeding , it happens when the fertilized egg attaches to the lining of the uterus — about 10 to 14 days after conception.
Implantation bleeding occurs around the time of a menstrual period. However, not all women have it. What Else Could It Be? A missed or delayed period, the most commonly reported first sign of pregnancy, could be caused by: Pending menstruation Excessive weight gain or loss Fatigue or exhaustion New workout regimen Hormonal imbalance Tension or stress Change in birth control usage Various illnesses Breastfeeding Nausea or morning sickness, the second most frequently cited symptom of pregnancy, might be explained by: Food poisoning Tension or stress Anxiety Change in hormonal birth control Other stomach ailments Tender or changing breasts, the third most noted pregnancy symptom, might be triggered by: Hormonal imbalance Change in hormonal birth control Impending menstruation Fatigue or tiredness can be brought on by: Tension or stress Exhaustion from working too hard Depression or other mental health struggles Common cold or flu New workout regimen Allergies or other ailments Lack of sleep Improper nutrition Pending menstruation What Do I Do Next?
