hey girls !!!

like 2 days ago i was experiencing spotting like reddish brown ( i stopped bleeding yesterday) & my friend told me it was implantation bleeding. i took a test and it came back negative, i looked at the test again this morning and now there seems to be another line making the test positive !!!! should i take another one ? ( i already made an appointment w my obgyn) i just need reassurance LOL going crazy over here
