pregnant??🤰🏽

i’m 16 years old , i haven’t miss my period or anything like that yet , but i been having this discharge. that i have never even have before which is weird for me . my period is supposed to come sunday but i took a pregnancy test and it came out positive i don’t know what to do or even if this is false one

the discharge is kinda brown , i been feeling so sick , kinda like throwing up in my mouth a little bit but nothing really come out i been having cramps here and there so what’s really going on if i’m not really pregnant

( clear blue can detect 5-4 days before missed period ) i have had one before but it was a negative test
