you might be showing the signs of being pregnant. home pregnancy tests are not very accurate as they try to detect the amount of hcg in your urine (and the levels can go up and down very easily due to various reasons).

1) if you want to do a home pregnancy test again, make sure you do it first thing in the morning as soon as you wake up.

2) take a beta hcg blood test in any lab (QR 200) and that will tell you the hcg values in your blood and this is 100% accurate.

BTW, hcg is only ganerated in pregnant women so if your hcg levels are above 5 mIU/ml then you are most probably pregnant and should visit a gynac.
