With ectopic development of the embryo, it is fixed outside the body of the uterus, for example, in the abdominal cavity or in the fallopian tubes. As for a missed pregnancy, then the development of the embryo stops and it dies. The result of the check is as follows:
• false positive - the second line will be slightly visible. If a woman has chosen a device that shows the number of weeks, then the result will lag behind the expected norm. If desired, several procedures are carried out per day using strips from different manufacturers;
• positive, and then negative or false positive - if the result indicates the development of the embryo, and the next day the strip disappears or a barely noticeable line appears, then perhaps the reason lies in the pathology;
• negative - indicates a decrease in the production of the hCG hormone. This is observed both with frozen and ectopic pregnancy. In this case, it is better to make several attempts at intervals of a day. A delay of 10 days and a negative indicator is a good reason to contact a gynecologist.
Any procedures aimed at determining conception at home must be repeated several times a day, or at intervals of 5-7 days. In addition, gynecologists advise using strips from different manufacturers.
