y’all i’m really scared

so i have a doctors appointment tomorrow that my normal doctor told me to go to, since this person specializes in that area. my period has been irregular for over a year now, long with irregular things coming with it. my doctor didn’t want to hear what was wrong since she can’t do anything, but she said since i’m 17 and haven’t had sex they shouldn’t go up and check out my area. but, with what’s happening and the fact my aunt has terminal cancer that began in her uterus, they’re probably gonna have to go up. (my aunt won’t even tell me the symptoms she had before she found out, because she wants me to suffer mentally, tho i highly doubt it’s cancer) the appointment is scary enough, but i’m really scared for the results (i’m pretty sure at this point, best case would be i’m just infertile or early menopause). google will probably tell me i’m dying, so i’m trying hard to stay away from that. maybe you ladies can help me figure out what’s wrong before the appointment to ease my mind?

i’m just scared, sorry if some of these are normal but they’re not normal for me (at least for the first two years) and the text at the bottom is from my last period like a few days ago, i stayed home from school same thing happened during day two just less pain.
