22 and Premenopausal help

Hi. I just turned 22. And 21 I went to the hospital for a cyst that ruptured (i get them frequently around ovulation) and

on the test results it says “ endometrial stripe measures 1cm in thickness” then under “Impression” it says in bold letters “thickened endometrium which may be a normal finding in a premenopausal patient. Please correlate with Beta HCG

Beta HCG says <2.4

Does anyone know what this means

Does this mean im premenopausal?

I haven’t been able to get pregnant either the past couple years. Could this be why?

I tried calling the hospital for kore answers but she said noone would help me except my dr but i went in through the emergency room because i dont have insurance.

Im scared :/
