Pregnancy Symptoms: First Trimester
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.

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

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.
