When you get pregnant 11 days after ovulation, some women may experience slight abdominal pain and a small amount of bleeding, which is considered to be caused by the destruction of part of the endometrium when the fertilized egg is in bed, the bleeding is relatively small and short, and it will be clean in 1-2 days, and the symptoms are not exactly the same for everyone with different body types. Most people do not have any symptoms 11 days after ovulation because the secretion of human chorionic gonadotropin in the body is relatively small and does not cause nausea and vomiting. Some women are more sensitive and experience breast swelling and pain and fear of cold, which are related to the increase of estrogen and progesterone levels in the body. If you have sex during ovulation and do not use contraception, you can go to the hospital 11 days after ovulation to have blood tests for human chorionic gonadotropin in your blood to determine if you are pregnant. If pregnancy is confirmed, with the increase of HCG content in your body, you will experience nausea, vomiting and general weakness around 6 weeks of pregnancy.
