It is possible to be pregnant if the ovulation test remains weakly positive, but it may also be caused by factors such as test paper failure or endocrine disruption.
A weak positive test indicates that a woman has ovulated or is about to ovulate, and if she has sex within 48 hours, she may be pregnant. However, if the ovulation test paper has exceeded its expiration date or is used in an incorrect way, it may also lead to a weakly positive test result, in which case the test result is usually not pregnant.
In addition, endocrine disorders in women, resulting in abnormal hormone levels in the body, will also affect the results of ovulation test paper to a certain extent, when the ovulation test paper shows a weak positive result is not necessarily pregnant.
It is recommended that women go to the hospital for an abdominal ultrasound or blood HCG test to determine whether they are pregnant.
