so question !!

back story : my little sister took 5 pregnancy test from 3 different stores. all said positive almost instantly. she had a little bleeding , thought it was normal. then she goes to this little clinic in our home town , they take a urine test , it’s negative. not pregnant. so she waits a week , takes another at home test. negative. waits another week , negative. then after 3 weeks , she takes another at home test because she’s still have symptoms & it’s positive. took more days later and it’s still positive . (no they haven’t had sex cause she’s been having some problems down there ever since she originally found out) …. today she is having some bleeding . brown & one clot !

so my question is , should she go to the ER ? do we think she’s pregnant ? or having a miscarriage? i’m at a loss . but she’s scared . & her bfs parents are terrible & basically telling her to stop listening to other people and to basically not worry about it.
