Heightened Sense of Smell
Gestational timeline: 1st Trimester & 2nd Trimester
Overview
Your sense of smell may become heightened during pregnancy. This is due to the increased production of hormones, such as estrogen and progesterone. You may be more sensitive to smells, both good and bad. You may also find that certain smells make you feel nauseous or queasy. It typically occurs during Weeks 2-3, 7-8, 11, 15, 19 (1st Trimester & 2nd Trimester) of pregnancy.

Other Symptoms Expected in These Weeks
Here are other common symptoms that typically occur during weeks 2, 8, 3, 7, 11, 15, 19:
Basal body temperature (BBT) Increase
Basal body temperature (BBT): Your basal body temperature (BBT) is your temperature taken first thing in the morning before you get out of bed. It is usually lower than your regular temperature during the day. During pregnancy, your BBT may rise slightly. This is because the production of progesterone increases during pregnancy, which can raise your temperature. A sustained rise in BBT can be a sign of pregnancy, but it is not always reliable.
Fatigue
You may feel more tired than usual during pregnancy. This is due to the increased demands of your body. Getting plenty of rest, staying hydrated, and eating a balanced diet can help combat fatigue.
