thank you for using health care magic,
test are not very reliable.. in early stage of pregnancy it can give false negative results.. go for more confirmatory test like beta hcg
level or ultrasound
.. consult near by gynecologist for it...
if pregnancy gets confirm then you can go under abortion
.. since you are in early stage it can be done only by using pills..
in future practice safe sex.. you can use pills or condom..
