Should i take another urine based pregnancy test to be sure?
Patient: My husband and i have an unprotected sex.. i was expecting my menstruation last june 15 ..but doesnt come.. i have been feeling a bit nauseated.. and now i am experiencing spotting and some cramps.. i have taken pregnancy test three days ago, and the result was negative.. my menstruation was irregular.. i am really confused.. should i take another urine base pregnancy tesy to be sure? Doctor: Hello dearI understand your concernUrine pregnancy test will give true positive result 7 days after the delay in the period. It has 98% sensitivity.So if you did not perform test after 7 days of delayed period, then go for repeat test.Better to go for blood HCG test as it is more accurate test and give positive result even 10 days after the sexual intercourse.Spotting, nausea could be due to hormonal imbalance, premenstrual symptoms, implantation bleeding/pregnancy.So you can repeat the test if you had did test 7 days before the expected period date.But I would suggest to go for blood HCG test as your period is irregular.Meanwhile avoid stress, take healthy diet, drink plenty of water and do regualr exercise.Hope this may help youBest regardsDr. Sagar
