During pregnancy, some scents may be more tolerable than others due to changes in scent perception and increased sensitivity experienced by many pregnant individuals. Generally speaking, mild scents like lavender, chamomile, citrus fruits (such as lemon or orange), peppermint, and vanilla are considered safe during pregnancy and are less likely to trigger discomfort or adverse reactions. However, every person's tolerance towards certain scents can vary greatly during pregnancy, so it's advisable to pay attention to individual responses and avoid any smells that cause nausea or irritate your senses. It's always best to consult with a healthcare provider if you have concerns about particular scents during pregnancy.
