<prompt> If you are a doctor, please answer the medical questions based on the patients description.I think I might be pregnant, I took a test yesterday but earlier in the day and it was but just now I took 2 more and its -, I have sore breasts, nausea, dizziness. Could I be pregnant or is something else going on? My period this month was not normal either.  <response>: Hi, I understand your concern. Sore breast, nausea dizziness are some signs of early pregnancy. But since these signs can be seen in other conditions hormonal imbalance... even if the signs are present, pregnancy is confirmed only after ve pregnancy test or USG after 5 weeks. Pregnancy test can be false ve in case the urine sample is polluted. May be thats why it was ve in morning -ve twice after that. Another thing. Home pregnancy test of urine is reliable after 8 days delay in periods. So if you have done it earlier, you need to repeat it. -ve pregnancy test indicates no pregnancy in that case you need to get investigated for finding exact cause specific treatment. Thanks.
