After having intercourse in the morning, there is no effect of having a gynecological or prenatal ultrasound. It is even less of a problem if you are having an abdominal ultrasound. During gynecological examination, it is usually to check for occupying gynecological lesions, such as uterine fibroids, cervical cysts, cervical cancer, ovarian cysts, ovarian cancer, etc. However, you need to hold urine after filling the bladder before doing these examinations to artificially create a transillumination window to check the posterior gynecological organs. If it is a prenatal test, there is no need to hold urine. If it is a check for early pregnancy, you still need to hold urine. In short, these tests are not related to morning intercourse.
