There is no direct relationship between having a cold after intercourse and the prediction of pregnancy. The symptoms of early pregnancy may be somewhat similar to those of a cold, such as dry vomiting, dizziness, weakness and loss of appetite, but early pregnancy is accompanied by menopause and breast swelling, while a cold does not show such symptoms, and a cold will show symptoms of respiratory infection such as nasal congestion, runny nose, sore throat, cough and phlegm. The cold after intercourse does not indicate pregnancy, there is no necessary connection between the two, women can combine their menstrual flow pattern to determine whether they are pregnant. If the normal menstrual period is delayed for 7 days or more, conception can be considered. It is recommended to check the blood HCG value at the hospital to make a clear diagnosis, or you can buy early pregnancy test strips to test yourself, but eventually you need to go to the hospital to make sure it is intrauterine pregnancy. If you are not pregnant after intercourse and have cold symptoms, it may be caused by cold and low immunity. It is recommended to go to the hospital for examination and the doctor will treat the symptoms according to the specific situation by giving acetaminophen, aminoglutethimide and other medications. If the patient is in a state of pregnancy preparation or suspected to be pregnant, it is recommended that he or she must tell the doctor and use the medication carefully so as not to affect the pregnancy and cause fetal malformation.
