ridiculously late period. help?!

Ma

i’m 14 and i’ve had my period for a few yrs, it was very regular up until december and then it just stopped. i’m a virgin and not rlly sure what’s going on. ik periods can b irregular for the first few yrs but not sure if i’m ok.

i was at a doctor after 2 months of skipped period and she told me that i was just underweight and wasn’t eating enough and that it would come back soon. i told my mum that it’s 8 months late and she seems to think it’s fine but i’m not quite convinced. she said it could b stress related?

id like to go to a gyno or someone who could tell me what’s happening but i’m worried abt what’ll happen when i’m in there(i’m only young so i don’t want anyone even if they’re qualified to b poking around there lmao). i’m also concerned that i could have pcos but it’s just an uneducated guess. i’m pretty clueless.

everything seems pretty normal, i get back pain as i usually do when i’m on my period and i still have discharge that hasn’t changed.

another thing that’s stressing me out is that i told some of my friends(which i thought i trusted but i don’t now) they keep saying things abt it and calling me a slut, telling my that i’m pregnant.

sorry for so much info. just asking for a friend and some advice on what could b the problem? a solution? and what would a doctor do to check it out!!

thanks xx
