Good morning, I have a subcutaneous implant for the 3rd time (which is valid for 3 years)now I have it valid until 2025.The problem appeared now because I didn't get my period, and supposedly I should have it (I always had it differently, but they were every 20 days 24 differently), now I haven't had it for 28 days, although I have lower abdominal pain and breast tenderness and nausea, But before yesterday I did two tests from morning urine and nothing, today I did 3 tests, including a stream and a negative one. Always for so many years intercourse has been in the middle to the end and never anything for so many years now I have thick white mucus and tenderness of the breasts and nausea and pain in the lower abdomen (intercourse was once from 20 days ago a week ago to the end) please please tell me if the white mucus or thick discharge is a sign of menstruation or what? Negative tests.
