<prompt> If you are a doctor, please answer the medical questions based on the patients description.I have taken lots of pregnancy tests and just last thurs it showed negative then i looked at it again a couple hours later and it showed positive took another one right after and it came out negative then changed to positive took one this morning and it showed negative I am 9 days late with some symptoms of being pregnant. I was just wondering idf I could be?  <response>: HI, I understand your concern. Actually, Pregnancy test of urine is said to be reliable after 8 days delay in pregnancy. False ve test is more likely than false -ve test. False ve can be due to polluted urine simple polluted collection container. I would suggest repeating urine test after 3-4 days with a boiled urine container careful collection of urine avoiding its contamination or burning urination or white discharge. In case of doubt blood Chat Doctor test will confirm.USG scan after 5 weeks pregnancy. Thanks.
