If the pregnancy test paper is two bars, it means it is positive and the patient may be pregnant. If the test line is lighter, it means it is weakly positive and further testing is needed for confirmation. If the test line is the same color as the control line, it is a strong positive, and the chance of pregnancy is more than 90%, in which case the blood chorionic gonadotropin can be further tested for confirmation. After the pregnancy is confirmed, an ultrasound can be done in a week or so to determine whether the pregnancy is intrauterine or extrauterine. If there are two bars on the ovulation test paper, you will need to determine whether or not you have ovulated based on the depth of the test line. If the test line is light in color, it is a weak positive, which means that you may not have ovulated or have already ovulated. If the test shows a strong positive, it means that you are ovulating and can choose to have intercourse.
