Pregnancy: Early in pregnancy, you may experience mild or light cramping. These cramps will probably feel like the light cramps you get during your period, but they’ll be in your lower stomach or lower back. If you have a history of pregnancy loss, don’t ignore these symptoms.

Uterus pain in early pregnancy is a common experience, and it has a range of possible causes. While most of these are not serious, some will require medical attention. During early pregnancy, the uterus is much smaller than it will be in the second and third trimesters.

Up to 80% of pregnant women experience nausea and vomiting, most commonly in the first trimester. Symptoms and signs that may indicate another cause include nausea and vomiting persisting past mid-pregnancy (approximately 20 weeks) and associated abdominal pain, fever, or diarrhea.

Sometimes the cramping or aches and pains you may feel can also arise due to soaring progesterone levels in early pregnancy. You may also feel a sharp pain, or what feels like a muscle spasm, in your pelvis due to the stretching ligaments around the uterus. You can read more about lower abdominal pain.

Many women experience similar cramping right before their regular menstrual period, but it’s a common early symptom of pregnancy.

It can be confusing during the first month because pregnancy (which is an average of 40 weeks long) is actually measured from the first day of your last menstrual period. Even though you likely ovulated and conceived only two weeks ago, technically, you’re considered to be four weeks along.

Nausea. As the pregnancy hormone hCG begins to make its way through your newly pregnant body, you may notice some feelings of queasiness—or nausea so bad it makes you puke. Morning sickness should really be called all-day sickness since it doesn’t discriminate by time of day.

When does a baby have a heartbeat? A baby’s heartbeat can be detected by transvaginal ultrasound as early as 3 to 4 weeks after conception, or 5 to 6 weeks after the first day of the last menstrual period. This early embryonic heartbeat is fast, often about 160-180 beats per minutes, twice as fast as us adults’!

Is it normal to be really tired at 4 weeks pregnant? It’s totally normal to be completely worn out and feel like you need a nap after tying your shoes at 4 weeks pregnant. Fatigue is one of the main symptoms of early pregnancy, and it’s no wonder—you’re growing a brand new person inside your body!
