Delay in menstruation for about 7 days after artificial insemination could be pregnancy. Artificial insemination is an assisted reproduction technique that involves injecting washed and treated sperm into a woman’s reproductive tract during her ovulation to fertilize her, and needs to be performed by a medical professional. Pregnancy is more likely after IUI when menstruation is about 1 week overdue, and can be confirmed with a blood or urine hCG (human chorionic gonadotropin) test. IUI is indicated for infertile couples with normally developing follicles, a normal range of motile sperm counts, a structurally normal female reproductive tract, and at least one patent fallopian tube, and can be performed during a woman’s natural or ovulation-promoting cycle. After confirmation of pregnancy by blood or urine hCG after artificial insemination, ultrasonography is also performed to determine if the pregnancy is a normal intrauterine pregnancy, for which you can consult a medical professional.
