You cannot test for pregnancy the next day after you have used 2,000 units of chorionic gonadotropin on the first day. Because the body injected 2,000 units of chorionic gonadotropin, it takes more than a week for the body to metabolize it, the accuracy of pregnancy monitoring at this stage is not high, and there will be the possibility of early false positives. After the drug treatment interval of more than a week can go to the hospital blood test whether the conception, if not blood test with early pregnancy test, then need to be more than 15 days from the coitus with test paper, so that the accuracy is higher. In addition, during the preparation for pregnancy, pay attention to supplement the body folic acid, relax the mind, do not be too nervous so that can increase the probability of conception. If you are not feeling well, you should consult a doctor in time.
