Yes, it is possible to be pregnant without experiencing tender and swollen breasts or nausea. Every woman's body reacts differently to pregnancy, and not all women will experience the same symptoms. While tender and swollen breasts and nausea are common pregnancy symptoms, their absence does not necessarily mean you are not pregnant. Other signs of pregnancy include missed periods, fatigue, frequent urination, food cravings or aversions, mood swings, and heightened sense of smell. If you suspect you may be pregnant but are unsure due to the lack of these specific symptoms, it is recommended to take a home pregnancy test or consult with your healthcare provider for further evaluation.
