9. Allergies
Pregnant women with soy allergies should not consume edamame or soy in any form. However, pregnant women who are not allergic to soy must also not take soy supplements without their doctor’s approval. Some signs of soy allergy are nausea, hives, itching, diarrhea, and flushed skin.
10. Risk of bleeding
Pregnant women who are on blood-thinning drugs must monitor their consumption of soy products. Soy is rich in vitamin K, which enables blood clotting and may work against blood-thinning medicines.
