When bleeding occurs after tubal imaging, it is normal for the bleeding to stop within 5-7 days. The main reason why bleeding occurs is that a catheter will be inserted into the cervix during the imaging period before the contrast medium can be injected, and the insertion of the catheter will lead to localized mucous membrane damage of the cervix, so bleeding will occur. It is recommended to keep the vulva clean and not to take a bath for half a month after the contrast, so as not to cause localized infection of the broken mucous membrane by pathogenic bacteria, resulting in a localized inflammatory reaction of the cervix. It is also recommended to observe in the hospital for one hour after the imaging, and leave the hospital only if there is no discomfort, and no coitus for one month and contraception for three months after the imaging.
