I think I'm pregnant

Kylee
Hey guys, Im 18 and unfortunately need some advice.. I'm 1 1/2 weeks late on my period and I'm experiencing some pregnancy symptoms, I bought a test but am to scared to take it quite yet... I'm terrified by the outcome and don't know how to tell my mom cuz she had me at this age and I don't want her to be dissapointed... What should I do???
