On December 25, 2020, I had sex with my boyfriend. The next day, I had my period and it has never happened again. I went to the doctor and he said I was normal. I had a blood test and the index was <0.1. But I have symptoms of pregnancy such as acne, lower abdominal pain, and breast tenderness. Doctor, can you tell me if acne, lower abdominal pain, and breast tenderness mean I am pregnant?
