Hi, Thanks for the query. I undrrstand your concern. Ectopic pregnancy can be diagnosed by - -Per vàginal examination in case of weak pregnancy test... when size of uterus is smaller than expected size.&there is mass/tenderness in tubal area. -Blood hcg testing done at 2 days gap... 2 or 3 samples show very slow rise in hcg levels (where as it doubles every two days in normal pregnancy) - Transvaginal USG scan would note tubal mass with gestational sac in case it is a tubal pregnancy. *In your case. if you are doubtful... repeat the urine/ blood test after a week ( blood test is possible nearing date of expected period & urine pregnancy test is best done after 8 days delay in period. In USG scan pregnancy is visible after 5 weeks of gestation. . Thanks.
