Slow deepening of the test paper does not mean ectopic pregnancy. Early pregnancy test paper can only be used to determine whether pregnancy, and can not determine the existence of ectopic pregnancy, if you want to clarify the existence of ectopic pregnancy also need to carry out a vaginal ultrasound examination. Early pregnancy tests are a means of determining whether a pregnancy has occurred by measuring the level of HCG in the urine. The shade of the color of the test strip or the speed at which it changes color may be related to the concentration of HCG. Early pregnancy tests can only be used to determine whether you are pregnant or not, and cannot indicate intrauterine pregnancy or ectopic pregnancy, so the slow deepening of the test paper does not mean ectopic pregnancy. Ectopic pregnancy is ectopic pregnancy, which can be determined by vaginal ultrasound or laparoscopy to determine the location of the gestational sac, so as to determine whether it is an ectopic pregnancy.
