What can cause all pregnancy symptoms including chloasma but not pregnant?

Several factors can cause symptoms that mimic pregnancy, including hormonal imbalances, stress, certain medical conditions (like polycystic ovary syndrome), or side effects from medications. Chloasma, or melasma, can occur due to hormonal changes from Birth Control pills or hormone replacement therapy. Additionally, anxiety and psychosomatic responses can lead to experiencing pregnancy-like symptoms without actual pregnancy. Always consult a healthcare professional for accurate diagnosis and guidance.
