What are some of the less known pregnancy symptoms?

Here are some lesser-known pregnancy signs and changes that can occur:

1. Heightened sense of smell: Changes in hormone levels can make your sense of smell more sensitive. You may notice a heightened awareness of certain smells, including food aromas or perfumes, which can sometimes trigger nausea.

2. Varicose veins: During pregnancy, increased blood volume and pressure can cause varicose veins to develop or worsen, particularly in the legs and vulva.

3. Linea Nigra: This is a dark line that runs from the belly button to the pubic bone. It's caused by increased pigment production due to hormonal changes.

4. Nasal congestion: Hormonal changes can also cause nasal congestion or a "stuffy" nose, leading to difficulty breathing through the nostrils.

5. Bleeding gums: Increased hormone levels can make gums more sensitive and prone to bleeding, especially when brushing or flossing.

6. Braxton Hicks contractions: These irregular and painless uterine contractions can occur throughout pregnancy, but they become more noticeable as the due date approaches.

7. Changes in hair and nails: Some women experience thicker, shinier hair and faster nail growth during pregnancy due to increased blood circulation and hormone changes.

8. Heartburn: Hormonal changes and the expanding uterus can cause the valve between the stomach and esophagus to relax, allowing stomach acids to reflux and causing heartburn.

9. Hemorrhoids: Increased pressure on the veins in the rectum due to the growing uterus can lead to the development or worsening of hemorrhoids, causing pain, itching, or bleeding.

10. Pica: This is an unusual craving for non-food items, such as dirt, chalk, or laundry detergent. While it's not entirely clear why pica occurs, it may be related to nutrient deficiencies.

11. Food aversions: Along with cravings, some pregnant women may experience strong aversions to certain foods or smells, which can be temporary or persist throughout pregnancy.

12. Increased saliva production: Hormonal changes can cause increased production of saliva, leading to a sensation of having a "full" mouth or feeling like you need to spit frequently.

It's important to note that every pregnancy is different, and not all women experience all of these signs or symptoms. If you have any concerns about potential pregnancy symptoms or changes, it's always advisable to consult with a healthcare professional for proper guidance and evaluation.
