Hi, thanks for asking in Healthcare Magic.
tests detect the presence of HCG
(human chorionic gonadotrophin) in urine. The HCG levels rise rapidly in blood within 6 to 8 days of implantation
(attachment) of fertilized ovum and this forms the basis of the pregnancy tests.
The pregnancy tests are usually very accurate. But if blood or protein is present in urine then it will give false positive results. In persons taking drugs like Diazepam
the result will be false positive. Since the pregnancy tests were positive twice the possibility of you being pregnant is high.
Changes in breast are the earliest feature in pregnancy. This is more marked in woman conceiving for the first time.There is a general enlargement and increased pigmentation. The classic "morning sickness" starts around 4 to 6 weeks of pregnancy.
But none of the signs and symptoms during the early period can confirm pregnancy. Other confirmatory tests like ELISA
are necessary. So visit your treating Doctor to confirm the diagnosis.
