Hello dear I understand your concern You have did not mention the about the delayed period.(how many days period was delay from the normal expected period date. If you have did the the pregnancy test 8-10 days after delayed period then it is confirmatory for the pregnancy. If you have did early then high chance of false negative and repeat the test. You have to go for blood HCG for accurate confirmation of pregnancy. If blood HCG and urine pregnancy kit is negative after 10 days of delayed period, pregnancy is not there. Light bleeding may be a implantation bleeding but must be with positive pregnancy test Missed period is definitive sign of pregnancy. Flutter in stomach, larger breast, dizziness and nausea may be variable symptoms of pregnancy. If pregnancy test will negative then other causes like hormonal imbalance, obesity, mental stress, pill use, old endometrial tissue should be rule out by consulting the gynecologist after undergo USG scan and reproductive hormone analysis. So first go for blood HCG and or pregnancy test and if negative then follow above advises. Avoid stress, take healthy diet , drink plenty of water and avoid high saturated fat.
