First Trimester Pregnancy Symptoms

Most people are interested in the first symptoms of pregnancy; particularly those that may reveal that pregnancy has occurred even before a missed period. The symptoms of pregnancy are different for each woman and they may even vary between pregnancies for the same person.

There are pregnancy symptoms that may only be experienced during your first trimester, that may continue into another trimester or occur throughout your pregnancy. Below is a list of pregnancy symptoms that are characteristic of the first trimester:

Pregnancy Symptoms: First Trimester

Implantation Bleeding: Although some women will not experience this or even notice it when they do, the only time this symptom will occur is during the first trimester when the fertilized embryo implants in the uterine wall. It may actually last for several weeks appearing as light spotting.

Missed Period: It is true that it is possible to be pregnant and to still have a period, but that is not what is expected. When pregnancy occurs you should stop having a period. This is a symptom of pregnancy that begins in the first trimester and continues throughout your pregnancy. If you experience bleeding it is usually break through bleeding or signs of a miscarriage, but it shouldn’t be a true period.

The first trimester is characterized by a rapid increase of hormones that support the development of your baby and trigger the changes in your body necessary to carry your child, give birth and breastfeed. Here is a list of symptoms of pregnancy that are triggered or caused by your pregnancy hormones:

  • Tender or swollen breasts
  • Fatigue
  • Lower backache
  • Nausea or morning sickness
  • Dizziness or fainting.
  • Changes in appetite
  • Headaches
  • Constipation
  • Mood swings

Increased basal body temperature: Your basal body temperature is the temperature taken orally using a basal thermometer. The basal temperature is tracked by individuals who are trying to conceive and monitoring for their ovulation. When pregnancy occurs, your basal body temperature usually rises over the next couple of weeks. This is a first trimester symptom of pregnancy. You may experience increased body temperatures throughout your pregnancy but this occurs for other varying reasons.
